iPhone: enable internal profiler doesnt work...

Hi,

i want to profile my unity-iphone project and i want to activate the internal profiler. Like the doku says, i changed in the "AppController.mm" the line to "#define ENABLE_INTERNAL_PROFILER 1". After saving and rebuilding my project, i get the following errors message:

ld: ldr 12-bit displacement out of range (5880 max +/-4096) in _AudioQueueAddPropertyListener$stub in _AudioQueueAddPropertyListener$stub from /Users/my_name/workspace/unity_iPhone/projectNameXYZ/Export/myexport/build/myapp.app/myappname
"Command/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/g++-4.2 failed with exit code 1"

Does anybody know what i have to do?

Please select deployment target "iPhone OS 3.0" or earlier. It is known Xcode linker issue with deployment targets "iPhone OS 3.1" and later.
