title: Xcode 4.3.1 three20 build errors when running Profiler
body: <p>I am updating an application (not developed by me) that uses three20.  I was successful in getting it to build and run on Xcode 4.3.1 which is great :o)  I am now concerned about memory leaks (no arc in the app yet) and want to run the app through the profiler.  When I try to do this (Product --> Profile) I get Three20 build errors again.  Specifically "Three20Core/private/TTExtensionInfoPrivate.h"file not found and a Shell Script Invocation Error in the three20/src/scripts/Protect.command: line 31
  line 31 in the Protect.command was added in to get the app built and running on this version of Xcode - it reads:  cd ${PREFIX}${PUBLIC_HEADERS_FOLDER_PATH}</p>
  
  <p>I take it that the profiler must use a different Header search path or Build Location?  </p>
  
  <p>Has anyone dealt with this issue before or have an idea for solving?</p>
