title: Where is my rails installation located? Where are the rails plugins?
body: <p>I'm trying to delete a plugin I installed for rails (paperclip). But I actually don't have any idea where I can find my local rails installation directory.</p>
  
  <p>So where can I find rails and rails plugins in my local file system?
  I have OS X.</p>
  
  <p>Or how can I uninstall paperclip from the command line?</p>
  
  <p>Thx!</p>
