title: pod install returns fatal error: SSL certificate issue?
body: <p>I just installed CocoaPods by following these instructions: </p>
  
  <p>Now I opened an Xcode project which has CocoaPods in it, I opened the terminal, went into that project folder and typed "pod install" as required, and I am getting an error back:</p>
  
  <pre><code>$ pod install
  Setting up CocoaPods master repo
  [!] Pod::Executable clone 'https://github.com/CocoaPods/Specs.git' master
  
  Cloning into 'master'...
  fatal: unable to access 'https://github.com/CocoaPods/Specs.git/': SSL certificate problem: Invalid certificate chain

  <p>I have no idea what this is about. Can someone help me? This is the first time I try to do anything with CocoaPods on OS X Mavericks.</p>
  
  <p>Thanks!</p>
