I've attached my updates to p5-math-pari's Portfile, which update the
version and integrate fetching pari's tarball into the port instead of
having the perl module fetch it itself.

The major thing is in pari-2.1.7/src/kernel/ix86/l0asm.c, first is that
ASM_UNDERSCORE needs to be set for __APPLE__ as well, then we run into the
issue that overflow and hiremainder are common symbols, which get lost when
the perl module bundle is built.  Combining Intel assembly with the Mac's
interesting linking put it outside my area of knowledge (eg, trying to make
those symbols not common, I ran into issues with other things being claimed
note to be relocatable).
