If I remember @jperkin correctly, the bulk builds are done on Illumos, 
which probably does have a different (i.e. newer) userland compared to 
Solaris 11.

I don't think that a mix of packages using native and pkgsrc versions of 
gmp and mpfr is a good idea, so I will keep

PREFER_PKGSRC = gmp mpfr

anyway and not try to solve this on a per-package level. And if the 
per-package solution depends on the exact derivative of Solaris, I think 
this will get way to complicated.
