title: Bundler is acting like a crazy person
body: <p>I accidently wrote <code>bundle update twitter</code> because I wanted to update the twitter gem. When I restarted the server (nginx with passenger) it yelled at me:</p>
  
  <pre><code>Exception PhusionPassenger::UnknownError in PhusionPassenger::Rack::ApplicationSpawner (Could not find rake-0.9.2.2 in any of the sources (Bundler::GemNotFound)) (process 31117, thread #&lt;Thread:0x00000100887358&gt;):
  </code></pre>
  
  <p>That was almost the end of my professional career as I contemplated suicide. But I'm on the first floor.</p>
  
  <p>One <code>bundle install</code> later everything works perfectly, only: <code>Your bundle is complete! It was installed into ./twitter</code>.</p>
  
  <p>I'm using RVM. Everything was fine until now. How do I revert back to the old and comfortable situation  where the gems didn't sit inside my rails folder?</p>
