At the moment we don't use mpir.h.

It should be possible for them to make a gmp-4.3.spkg. I don't see any
technical hurdles there.

Perhaps there will be some doctest failures due to different gcd
functions being called, I don't know.

Someone needed to fix the gmp spkg anyway. It was severely broken, and
GMP also didn't compile on some of the planned supported archs.

I'll let Michael give a more canonical answer.

Bill.
