I get the following error when attempting to run
cap production deploy
DEBUG [dc362284] Bundler::GemNotFound: Could not find json-1.8.1.gem for installation
DEBUG [dc362284] An error occurred while installing json (1.8.1), and Bundler cannot continue.
DEBUG [dc362284] Make sure that `gem install json -v '1.8.1'` succeeds before bundling.
rvm install 2.1.0
rvm use 2.1.0
gem install json -v '1.8.1'
Building native extensions. This could take a while...
Successfully installed json-1.8.1

So after a half day on this and almost immediately after posting my question I found the answer. Bundler 1.5.0 has a bug where it doesn't recognize default gems as referenced here
The solution was to update to bundler 1.5.1 using
gem install bundler -v '= 1.5.1'
