I second the answer by tsega (updated by coreyward). "bundle package" is the generic answer.

The poster didn't ask WHETHER to freeze his gems. He wanted to know HOW. Answers like "Just don't do it" aren't helpful at all. Yes, it turned out his specific problem was a little different than that, but while "bundle package" might have been overkill it still solves the problem.

I have worked on a lot of systems, and on some you just don't have full access. Installing gems on some systems just isn't an option. So unless you package them, in general you're screwed. There are different workarounds for different hosts and systems, but none for some.
