PROBLEM:
bundler fails to build ffi and so my rails apps are broken in my development environment.
None of the posts that I've read have solutions that work for me. I get the same error in a number of rails apps.
What other troubleshooting steps can I take?
How do I fix this issue?
BACKGROUND:
After an upgrade to Mountain Lion from Snow Leopard, Xcode upgrade, Clean Homebrew install, I did a clean install of rvm. Now I am trying to recreate the gemsets used by my rails apps. I did:
gem install rails -v3.2.16 (to get the base rails gems installed)
rvm gemset import ruby-1.9.3-p545@CLIENTNAME.gems (to import gems)
bundle install (to install dependencies and resync gemfile.lock)
ISSUE:
bundle install fails with this error message:
An error occurred while installing ffi (1.9.3), and Bundler cannot continue.
Make sure that gem install ffi -v '1.9.3' succeeds before bundling.
The complete gem_make.out is here: https://gist.github.com/mattmartini/b2f8ad3b4e6c57325d38
The mkmf.log is here: https://gist.github.com/mattmartini/d3256cb52e5eafb2346b
The config.log is here: https://gist.github.com/mattmartini/69407e118e92cadda2b0
I would like to stay on ruby 1.9.3 as the Production servers are using this.
OBSERVATIONS:
One of the errors thrown is that 'C compiler cannot create executables' - this is not true. I can compile C programs and bundler built nokogiri without a problem.
I did just notice that libffi, which was installed (along with gcc46) by rvm, is keg only. Would bundler be able to use the lib in creating the gem?
ENVIRONMENT:
Mac OS X 10.8.5 (Mountain Lion)
Xcode 5.0.2 (command line tools installed)
Homebrew 0.9.5 (recent fresh install)
rvm 1.25.25 (stable)
ruby 1.9.3-p545
libffi 3.0.13 (brew via rvm)
gcc46 (brew via rvm)
REVIEWED:
I reviewed a number of posts of similar issues, but none had a solution that worked for me, including:

Note I had a bunch of stack overflow links here but I couldn't submit this question with them.
