One of the things I want to do is to install a few gems into the chefdk installed on the system if they don't exist. I thought it would be simple enough to just shell out and run the chef command to install these gems (i.e. `chef gem install kitchen-ec2` but calling the chef command, or indeed the ChefDK ruby from within my bundle results in an error stating that a gem can't be found.

I’ve noticed recently that when running any gem commands inside of a bundler’d ruby process, you need to wrap everything in
Bundler.with_clean_env do; your_gem_related_code; end;
This used to work fine without the clean env thing, so I think there is a recent change to either bundler or rubygems that caused this.

You’re definitely crossing the streams here. Bundler is installed to the system ruby, and you seem to have your environment variables set in a way that makes ruby load stuff from there. As Brandon mentions, `chef shell-init` should fix this.

Aside from the above suggestions, run `env` and look for any GEM_* variables. rvm in particular works by setting these, if you’re an rvm user, there is a plugin for it to use ChefDK (but I can’t recall the specifics, sorry).
