I actually knew that the flags were overridden, I included "-fPIC" in
FFLAGS and "-undefined dynamic_lookup" in LDFLAGS because I saw they
were in the default build.  I didn't know that problems with that were
related to the import problem, so thank you for making that connection
for me.  Does anyone have any suggestions about how exactly my flags
are wrong, or some method to figure out what's wrong?  I've included
snippets of the build logs from the original build and from my build
in case they may be useful.

It looks to me like all of the flags are the same except for the
architecture related ones.  Ideas anyone?

Thanks,
