Comment (by macsforever2000@…):

 A couple of notes:
   - The latest Xcode for Mac OS X 10.7.5 is version 4.6.3 which you should
 update to.
   - The error "{{{cannot run C compiled programs}}}" means that the Xcode
 command lines tools are not (correctly) installed.

 I believe that this ticket should be closed as invalid.
