I am at wit's end. Have installed and reinstalled Qt SDK 2.1 on OS X 10.7.5; building from Qt Creator; keep getting these messages from the linker:

ld: warning: directory not found for option '-L/tmp/qt-stuff-85167/source/qt-everywhere-opensource-src-4.8.1/Desktop/Qt/4.8.1/gcc/lib'
ld: warning: directory not found for option '-F/tmp/qt-stuff-85167/source/qt-everywhere-opensource-src-4.8.1/Desktop/Qt/4.8.1/gcc/lib'
ld: can't map file, errno=22 for architecture x86_64
There is indeed no such path. The correct reference would be
/Users/tommy/QtSDK/Desktop/Qt/4.8.1/gcc/lib

Putting the following in the .pro file adds the correct Makefile phrases, but does not get rid of the incorrect ones:
LIBS += -L/Users/tommy/QtSDK/Desktop/Qt/4.8.1/gcc/lib
LIBS += -F/Users/tommy/QtSDK/Desktop/Qt/4.8.1/gcc/lib
I cannot find the source of these bogus paths. Does anyone know how to fix this?
