ERROR: Failed to build gem native extension on Mavericks

Question

I\'m attempting to run bundle in my Rails project on OSX 10.9. It fails when getting to the pg gem with this error:

Gem::Installer:

Also make sure that you've upgraded Xcode to re-install command line tools on Mavericks. In terminal type:

xcode-select --install

Then follow the prompts.
