What is that?!? That's not an Apple compiler and it's broken as you can see from the config.log:
It's the GNU C compiler version 3.3.4.
configure:32439: gcc-dp-3.4 -o conftest -g -O2 -I/Volumes/muffin/ DarwinPorts/include -L/Volumes/muffin/DarwinPorts/lib conftest.c - framework vecLib -lg2c -lgcc_s -lSystemStubs -lSystem -lcc_dynamic -lm >&5 gcc-dp-3.4: vecLib: No such file or directory cc1: error: unrecognized command line option "-framework"
This just means it doesn't support -framework. This is actually the answer to my original question. Apparently -framework is supported in stock gcc 4.x.
You should definitely use Apple's compiler, stock GNU gcc is NOT the same as Apple, because there are many features that Apple folks have added. You should check out the Apple branch from GNU.
It might not be such a good idea to be too dependent on Apple's gcc. There are compilers from IBM and Intel that people may at some time be interested in using. Kjell
