How do I make sure ':MakeGreen %' uses bundle exec ..?

I'm getting this in my status line..

You have already activated rspec-core 2.13.1, but your Gemfile requires rspec-core 2.8.0. Using bundle exec may solve this. (Gem::LoadError)

This rubygems plugin: rubygems-bundler is supposed to fix this usability issue. It is bundled in rubygems 2.0 which is distributed in Ruby 2.0. For Ruby 1.9 and older, just install this gem to see if it works.

That solved it, thanks. I had to also run gem regenerate_binstubs as per the README at https://github.com/mpapis/rubygems-bundler
