Now that Rails and many other gem/plugins have moved to github, there needs to be a better way to know where to get things from. The first thing I did was add github as a source (sudo gem sources -a http://gems.github.com/). How do I know where the gem came from once I install it? For example, Capistrano 2.4 seems to be in both places. Which one do I get when I install? If installed from rubyforge, but github gets an update, will gem update pick it up?
Do I need to go through all my gems and re-install if there is a later version on github?
Plugins are even more fun.
Any suggested courses of action for managing my gems in plugins?
