ahh, yes I was answering a different question.

To answer yours - in some cases bundle install --local would work, but 
only if the dependencies available locally are satisfactory (have you 
looked into using this instead of your approach?). Otherwise bundler_ext 
would work too, since it simply ignores versioning, and "loads" (not in 
ruby sense of the word) the latest gem version available.
