Macports/rvm/svn connection issue behind a proxy and firewall - proxy

Question

I am behind a corporate firewall that won't let me rsync out, and requires a proxy for HTTP/HTTPS. I'm having trouble with rvm breaking at the macports step in this environment.
To summarise:
I am trying to do rvm install ruby-1.9.3-p286
rvm wants to use macports.
macports wants to update using rsync, but I can't rsync out.
I set up a local macports source repo, but it doesn't seem to help - macports still wants to use rsync.
A suggestion on a similar question suggested changing port selfupdate to port sync in rvm's scripts. But that didn't help - macports then dies trying to do an svn update
But I can do the svn update manually fine, so I don't understand where the problem is.
Here are the details:
I followed this guide for using macports behind a firewall, by checking out the repo locally, and setting the following in /opt/local/etc/macports/sources.conf.
#rsync://rsync.macports.org/release/tarballs/ports.tar [default]
file:///opt/local/var/macports/sources/svn.macports.org/trunk/dports/ [default]
The only place I differed from the guide was I installed macports for 10.8 rather than 10.5.
However, rvm's macports seems to still use rsync for some reason:
$ rvm install ruby-1.9.3-p286
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.8/x86_64/ruby-1.9.3-p286.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Installing requirements for osx, might require sudo password.

This is very similar to this question, where the answer suggested the following change:

{

}

Unfortunately, that results in the following:
$ rvm install ruby-1.9.3-p286

This is strange, because I can run that svn command fine:
$ /usr/bin/svn update --non-interactive /opt/local/var/macports/sources/svn.macports.org/trunk/dports
At revision 107532.
It's not a user permissions/profile issue, because root can run that svn command fine too:
$ sudo /usr/bin/svn update --non-interactive /opt/local/var/macports/sources/svn.macports.org/trunk/dports
At revision 107532.
I assume something in the chain isn't seeing the proxy correctly. However:
My proxy is correctly set in the http_proxy and https_proxy environment variables
It is also set in ~/.subversion/servers (as the variables http-proxy-host and http-proxy-port in the [global] section)
And it is also set in /opt/local/etc/macports/macports.conf (as the variables proxy_http and proxy_https)
Other information:
ruby 1.8.7
rvm 1.21.4
OSX 10.8.3
MacPorts 2.1.3
Let me know if there's any other information that could be useful.
My question is How can I get port sync to work in this environment? (Which I am hoping will also fix rvm)

Answer 1

As a workaround to get you going try:
rvm autolbs read-fail
It will not install packages automatically - it will fail in case any packages are missing and will let you know names of this packages, just install them manually with macports and it should be fine.
Other solution would be switching to:
rvm autolibs homebrew
to use homebrew instead of macports, or:
rvm autolibs rvm_pkg
to detect what is already installed with pkg-config and try to install rest with the old rvm pkg install ....
