You should not have to reinstall your gems. However, if you get funny
errors, then that would be the first thing to do (especially with gems
that have native extensions).

As for the other part of your question, you really want to do a Google
search. It will give you a native installer as the first link

If that's not your style, then try the DarwinPorts or Fink package managers.

You can always download the source code and install your own Ruby.
