-------------------------------+--------------------------------
 I have found two other tickets with the above title but the claim is the
 problem was fixed.  It is not for me.  I am running on OS X Lion (can not
 up grade due to 2006 hardware limitation).  Xcode if 4.6.3

 Here is the log file for libpng
