Fang,
You have to be extra careful with gmp because upstream doesn't
use the standard config.guess (which would make configuration much
more bullet proof).

If you examine the build log (ours should match), the failure is happening
when a .libs/libgmpxx.4.dylib-master.o is being linked, which happens to
be the only object that is i386, while all others are x86_64 (using file
*.o). the i386 intermediate step causes x86_64 symbols to be lost
Hi,
It looks like the libtool script is dropping the -m64 during link.
Recall that path-prefix-10.6's g++ (compiler_wrapper) is set to i386
(32b). This is why libgmpxx.4.dylib-master.o is built for i386, which
causes subsequent links to libgmpxx.dylib (x86_64) to fail.
