title: Compiling PJSIP for use in iOS 5
body: <p>I know iOS 5 is still under NDA, but I don't think this will violate their terms.</p>
  
  <p>When I try to compile PJSIP for xcode for use within iOS 5, it dosen't find gcc. "Cannot find gcc for iOS 5 SDK" is the error I get. Is there any way to remedy this? Thanks!</p>
