According to:

-arch is a good start

Have a look at this as well:

It mentions additional CFLAGS you need to set.  I was pointed to this
document when playing with fat binaries on OS/X using pkgsrc.  There may
be some hints in there for you as well.

If you could say what version of OS/X your on, what architecture your
build host is and name a package you're having issues with then I might
be able to help you out a little more.
