I manually built Ruby 1.9.2 on Snow Leopard. Now I can’t find my old GEM files. I’m guessing they're in a different path now or something. So I have three questions:

  • What is the "old" gem path, where gem install sinatra puts the sinatra gem?
  • What is the "new" gem path, which is set when I build Ruby manually?
  • How do I change it so Ruby finds my gems again?
