I've been doing quite a bit of research on this issue the last week or so but haven't found a solution that works for me, it's very frustrating. Hopefully somebody can point me in the right direction. Here's the error I recieve

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

An error occurred while installing atomic (1.1.12), and Bundler cannot continue. Make sure that gem install atomic -v '1.1.12' succeeds before bundling.

This should work:

gem install atomic -V

And then:

gem install rails -V

The -V is for Verbose. You'll see what happen. It worked for me on a Linux box, when gem update didn't.

You also need to have the latest rubygem / bundler.

This happened to me because I didn't have the right version of XCode Developer Tools for OS X Mavericks. Then when I tried to update it, it said it wasn't available from the Software Update server. Details here.
