title: Podfile not downloading the latest versions of pods
body: <p>I am using cocoapods for my company project and I am having an issue regarding getting the latest pods.</p>
  
  <p>In my Podfile, I have many pods but my pain point is the optimizely pod.</p>
  
  <p><strong>pod 'Optimizely-iOS-SDK'</strong> - this should get the latest pod version but it doesn't. The latest version is 1.2.2 but this gets 1.0.78.</p>
  
  <p>When I make a specific version pod:
  <strong>pod 'Optimizely-iOS-SDK', '1.2.2'</strong>
  This complains:</p>
  
  <p>[!] Unable to satisfy the following requirements:
  - <code>Optimizely-iOS-SDK (= 1.2.2)</code> required by <code>Podfile</code></p>
  
  <p>Cocoapods version: 0.39.0</p>
  
  <p>OS X: El Capitan</p>
  
  <p>Ruby version: ruby 2.0.0p645</p>
  
  <p>I would appreciate any pointers as to what am I doing wrong.  </p>
  
  <p>Thanks</p>
  
  <p><strong>EDIT</strong>: My main problem is that without mentioning any version number why is it getting the older (1.0.78) version and not the latest version?</p>
  
  <p><strong>Update</strong>: pod install --verbose</p>
  
  <p>-> Installing Optimizely-iOS-SDK (1.0.78)</p>
