Thanks a lot for your reply, Jeff! I think I figure out why I got this trouble but am still looking for a way to work around it. The Mac I have has a 64-bit processor but its kernel is 32-bit. When I installed gnu-gcc, it identified the architecture as x86_64--I cannot install it if I force it to be i386. But the OMPI treat the arch as i386. If I try to force it to be x86_64, I got the problem I mentioned before....
