Macports Installation required - macos

I am planning to upgrade my OSx to latest version. I just wanted to ask that will i be required to install Macports again ? Or upgrading it simply will make it work accordingly with the new OSx. My current OSx is 10.9.4 and i am upgrading to the latest one.

Your MacPorts installation will not just work after a system upgrade. You need to follow the instructions in the MacPorts Migration Guide.

Installing Bakefile in Mac osx 10.11

I have been trying to install bakefile(v0.2.9) in mac osx 10.11. Whenever I try to install bakefile using the dmg file I get The installation failed.The installer could not install the software because there was no software found to install error.
I even tried building it from the source code(v1.2.5.1 from github). I built it using the sudo make command.However sudo make install command throws No rule to make target install.
Is there any other way to install bakefile in macosx 10.11?
Edit :
Finally I managed to install the bakefile 0.2.9 in osx 10.11. I can't use the latest version as it does not supports the bakefile we have been using in our projects.
Though the installation is successful,I get the segmentation fault 11 when I try to build the bakefiles(.bkl). Some of the forums suggested that the problem could be associated with python 2.7. I followed all the steps needed to resolve the issue. But none of them helped.
I have been using python 2.7.11. How can I avoid this segmentation fault?
I advice against using the legacy 0.2.9 version.
I even tried building it from the source code(v1.2.5.1 from github).
You didn’t, that’s the problem — you tried to build a very different version, 0.2.9 != 1.2.5.1. The relation between these two branches is explained at http://bakefile.org — they are incompatible and different.
If you want to build 0.2.9 from sources, you need to download and build 0.2.9.
If you want to use the 1.x version, you can download packaged “binary” version, as explained at https://github.com/vslavik/bakefile
P.S. You don’t need to, and shouldn’t, use sudo when installing somewhere you typically have access to, such as /usr/local on OS X.

Can I install emacs 24.5 on OS X El Capitan without deleting the native OS X emacs?

I want to install the latest version of emacs, but if I do this will it be in conflict with the version that comes pre-packaged with os x? Do I need to delete the native emacs? Also, it seems emacsforosx.com is a popular option, but I lot of people swear by homebrew... why would I go with one option over the other?
There is no reason to remove the system-supplied Emacs; any well-behaved, properly packaged third-party version will install fine alongside, not over, the system binaries and libraries.
Installing a current version of emacs is normal practice because the OSX provided version is outdated. You have a number of options, but I've found using the 'homebrew' method the easiest.
Due to changes in OSX 10.11, you need to take some additional steps when installing homebrew. If you already have homebrew installed, you will probably need to 'fix' the permissions on /usr/local. If you don't have homebrew installed, then there are some additional steps you will need to take to create the /usr/local path. This is documented on the hombrew site at El Capitan and Homebrew

Git for Mac fails to launch: "illegal instruction"

...I've looked pretty carefully (I believe), and have been unsuccessful at getting an installation of Git for my Mac.
For various reasons, I'm running 10.6.8 of Mac OS X and will not be changing that anytime soon.
I've already gathered and installed the bundle exposed here:
https://help.github.com/articles/set-up-git
The installation instructions are pretty clear, and it's obvious to me that the package installed. But any attempts to use the git client from the command line result in an "Illegal Instruction" error.
I've sifted pretty carefully through information available here:
http://git-scm.com/book/en/Getting-Started-Installing-Git
There is another bundle that seems to be available. It is called "GitHub for Mac 1.7.5, but it appears to require Mac OS X 10.7 or later.
Has anyone else encountered this difficulty? Must I build from source?
I'm a couple of hours of reading and hacking into this effort? Is there something obvious that I've not considered?
Yes, I've had the same exact problem, and what I did is installed an earlier build from here:
https://code.google.com/p/git-osx-installer/
I'm running 10.6.8 and installed the newest build there, 1.8.4.2
SourceForge only has 1.9.0 and 1.8.5.2
http://sourceforge.net/projects/git-osx-installer/reviews?source=navbar
Someone on the reviews said they had trouble with both and went back to 1.7. I would try that if 1.8.4.2 doesn't work.
I was able to run the config commands without an illegal instruction error, at least.
I had this problem and was able to install a working version using Homebrew.
# first uninstall the broken version
# mount the DMG for the broken version using Finder
# "type" this with the tab key! it saves typing and fixes the version number
cd /Volumes/Git\ 2.0.1\ Snow\ Leopard\ Intel\ Universal/
./uninstall.sh
# make bash forget about the uninstalled binary
hash -r
cd
# now install the working version
# assumes you have Homebrew installed
brew install git
git version
I had this today on Snow Leopard after running the suggested git installer from git-scm. Really horrible. Found that installing Macports using their old Snow Leopard package and then
sudo port install git +svn +doc +bash_completion +gitweb
installs git plus its dependencies and git now works fine; version 1.9.3 installed and working on 10.6.8.
I had the same problem. There are various methods for downloading and installing git - Try macports or homebrew. The thing that finally worked for me was having xcode 3.2.6 installed with the additional command line tools - version 3.2 that comes with the leopard install disk wasn't enough. You can install xcode etc. from the disk and then run software update to upgrade it to 3.2.6.
The latest build for Snow Leopard in the official git-osx-installer repo is Git 2.3.5 currently. You can download it from http://sourceforge.net/projects/git-osx-installer/files/git-2.3.5-intel-universal-snow-leopard.dmg/download using web browser. This installation works for me on OS X 10.6.8.
Or you can check yourself for a newer version: http://sourceforge.net/projects/git-osx-installer/files/
Yes - it seems that it does not support the older OS version (mine was 10.6.8). I upgraded to the newest Mac OS 10.9.4 (the installation will take a while), reinstalled the Git software (note that it will ask for xcode to be installed, which I proceeded), and everything works fine from there. Hope this helps.

To quote:
Does GitHub for Mac run on OS X 10.6 Snow Leopard?
No, GitHub for Mac requires OS X 10.7 (Lion) or higher.
We made this decision because the app relies on a number of
technologies which are not available in Mac OS X 10.6 or earlier. We
want to provide the best experience possible for the app's users, so
we've made the choice to only support 10.7 and above, and not make
earlier versions available.

Mac 10.6.8 - Homebrew - Xcode not installed

I just started using Homebrew, but I am running into trouble right away.
The problem is that brew doctor keeps telling me 'Xcode not installed'.
I have seen a similar question (15891818) on this topic, but there was just a partial solution for Node.js
I first had Xcode 3.1 installed, and when I ran brew doctor it correctly informed me my Xcode was an old version, and told me to upgrade to 3.2.6. So I downloaded Xcode 3.2.1 from the apple site, after that I did a Software Update and upgraded to 3.2.6.
After this, Homebrew just doesn't find the Xcode installation at all. (I even restarted my computer)
I am on OS 10.6.8.
any ideas?
Thanks a lot
homebrew needs gcc, which i got from here without having to install xcode https://github.com/kennethreitz/osx-gcc-installer

"The installed version of Xcode (3.1.4) is too old" error in port after installing Xcode 4.3

A have freshly checked-out from svn, built and installed MacPorts. I have installed Xcode4.3. I get the following error when trying to call "sudo port install X":
Error: The installed version of Xcode (3.1.4) is too old to use on the installed OS version. Version 4.1 or later is recommended on Mac OS X 10.7.
"xcodebuild -version" returns:
XcodeComponent versions: DevToolsCore-1809.0; DevToolsSupport-1806.0
BuildVersion: 10M2518
I have recently updated MacOS to Lion and I used to have an older version of xCode in SnowLeopard, which didn't work in the new system. I didn't uninstall it explicitly, but I also don't find any trace of the old Xcode on my system.
Any ideas? Please, help!
Xcode 4.3 should prompt you to remove any older versions when you run it for the first time, but check to make sure you don't have a /Developer directory anyway.
Have you run sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer? What does xcode-select -print-path tell you?
I just encountered the same problem as the OP and found this thread in a search. Installing Xcode 4.3 today didn't prompt for removal of older version (at least that I recall seeing), and /Developer hierarchy is still present. Renaming to /Developer.ex solved MacPort's problem. Can I safely delete /Developer completely?
