Comment(by jmr@…):

 I am taking this seriously and trying to help. I am attempting to
 determine precisely what the problem is. A Core 2 Duo is a 64-bit CPU, and
 as such your machine can run 64-bit code (and will in fact prefer to do so
 in 10.6). I asked what arch libmpfr.dylib and libgmp.dylib are in order to
 determine which port is not applying your chosen build_arch correctly. You
 can find out with this command:
 {{{
 lipo -info /opt/local/lib/libmpfr.dylib /opt/local/lib/libgmp.dylib
 }}}
