| AC_MSG_ERROR([Cannot compile --with-bignums without the GMP library | It is highly recommended that you install a working GMP | library on your system as that will add features to Pike | required by many applications (such as Roxen).

Considering that Pike now needs Nettle to have at least a semi-usable make verify, maybe adding such a test to configure for Nettle too wouldn't be a bad idea?
