 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.
