OK, I think I did that successfully, but I probably haven't pointed
mpfr to the right place.

so the defualt prefix for gmp being /usr/local if I put
--with-gmp=/usr/local  that should work?    I was expecting the
gnu-ish defaults of /usr/local to be picked up and handled correctly
automatically, so I wondered if I had to point CFLAGS or something
at the actual source directories..
