title: bundle install not installing all dependencies
body: <p>I am on Mac OS X, and when I run sudo bundle install, it installs several gems on the target machine:</p>
  
  <pre><code>Installing ptools (1.2.1) 
  Using thor (0.14.6) 
  Using railties (3.0.5) 
  Using rails (3.0.5) 
  Installing rails_config (0.2.4) 
  Using shoulda (2.11.3) 
  Your bundle is updated! Use `bundle show [gemname]` to see where a bundled gem is installed.

  <p>So, it should be safe to assume that dependencies are resolved for the app, and things are ready to go. But they are not.</p>
  
  <p>When I run rails console, I constantly receive output about more and more and more and more unresolved dependencies:</p>

  <p>Is Rails really this difficult? Do I really have to install dependencies manually, one by one? What am I doing wrong?</p>
