There is only one match, in /usr/local/include/gmp.h:
  gmp.h:#define mpz_abs __gmpz_abs

There are both dynamic (.dylib) and static (.a) versions of gmplib. So  
perhaps the static is linked more than once.

It might happen if say you expect the dynamic library ending with .so  
instead of .dylib, or if using the wrong dynamic linking flag.

There is no problem with the stable branch, 1.8.8. So perhaps you  
might check what you do differently.
