I'm really sorry I answered this question. I personally hate
macports, but it has its own version of cmake that won't work with the apple
compiler:
/opt/local/bin/cmake -DCMAKE_CXX_COMPILER=/opt/local/bin/g++
-DCMAKE_C_COMPILER=/opt/local/bin/gcc ..
make VERBOSE=1
/opt/local/bin/g++ -Wl,-search_paths_first
-headerpad_max_install_names CMakeFiles/test.dir/test.cc.o -o test
Regards,
Juan
