bundle failure under OS X 10.9 (Preview 3) - macos

Question

I'm trying to run "bundle update" on OS X 10.9 but it's failing with the following error message:
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Xcode 5 (Preview 3) has been installed and so are the command line tools. Here is some relevant info:
gcc --version
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX10.9.sdk/usr/include/c++/4.2.1
Apple LLVM version 5.0 (clang-500.1.61) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin13.0.0
Thread model: posix
brew update
Already up-to-date.
rvm requirements
Installing requirements for osx, might require sudo password.
Certificates in '/usr/local/etc/openssl/cert.pem' already are up to date.
Requirements installation successful.
I'm not having any issues installing any version of Ruby so far (using rvm). Does anyone have any idea?
Thanks,
Francis

Answer 1

Make sure your default ruby is 1.9.3-p448. rvm --default use 1.9.3-p448

Answer 2

For me the issue was resolved by installing xcode command line tools. In terminal run:
xcode-select --install
and then select install in the popup.
I had recently installed xcode 5 and I guess I needed to run the above command after the install and I didn't and somehow that caused bundle update to fail.

I had the same issue , the problem was when upgrading to OSX 10.9 (mavericks) I didn't confirm that I agreed to the license agreement for Xcode . if you type the following
gcc --version
you should get "You have not agreed to the Xcode license agreements."
once agreed everything worked fine
