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/](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?
