title: Issues installing CocoaPods
body: <p>I'm trying to get CocoaPods set up in OSX (I'm running 10.8.2) - so I run </p>
  
  <p><code>sudo gem install cocoapods</code> </p>
  
  <p>It succeeds and I get - 'Successfully installed cocoapods-0.17.2
  1 gem installed'</p>
  
  <p>Then...I try <code>pod setup</code>  '-bash: pod: command not found
  '</p>
  
  <p>How do I get command line to recognize this command?</p>
