Gem versions are important due to dependency pinning problems w/ Berkshelf, Chef, and Vagrant
circa March 15th, 2013. 

The older version of chef won't impact the version of chef that gets provisioned on your vagrant
box, it's just for loading the knife.rb configuration.

Use bundle exec if you want these things to operate together correctly.
$ bundle exec vagrant up solo
$ bundle exec berks upload
etc...
