Thanks Jakub, I had missed that. It's actually much simpler. Karsten, you need
to ask Gaurav to build his GMP/MPFR/MPC libraries with an explicit build
parameter:
./configure --build=x86_64-apple-darwin14.0.0
(for Yosemite). Otherwise, the GMP library is not portable. And if I recall
correctly, MPFR and MPC use the GMP settings for their own compilation.
