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.

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'
