title: Unable to find a specification for `Mapbox` installing with CocoaPods for iOS 7
body: <p>I am building an app targeted to iOS 7 and I want to use Mapbox.  I added </p>
  
  <p>pod 'Mapbox'</p>
  
  <p>to my Podfile, but 'pod install' responds with:</p>
  
  <p>[!] Unable to find a specification for <code>Mapbox</code>.</p>
  
  <p>I cannot change back to platform :ios, '5.0' because I have other libraries that require the later version.  Is there a CocoaPod for MapBox that works with iOS 7?</p>
  
  <p>Thanks!</p>
