I have this functionality in GemInstaller (use --print-rogue-gems
option with an empty config):

http://geminstaller.rubyforge.org/documentation/tutorials.html#bootstrapping_your_geminstaller_config

However, I believe Bundler is a better way to solve these problems.
People should be specifying gems on a per-app or per-environment basis
instead of relying on system gems anyway.

Future versions of Bundler will also allow you to version and save the
entire dependency tree as Bundler has resolved it (without requiring
you to check in .gem files in cache dir, as is currently the case).
