+<PRE>Hi again,

+no idea what's going wrong. normally pycrypto should fall back to _slowmath (a pure python implementation) when gmp is

+not installed meaning _fastmath is not available (_fastmath is a C implementation using gmp).

+Maybe you could prvide some more information, like python version, pycrypto version, is gmp installed?

+Also it would be a good idea to provide a small/minimalistic example demonstrating the problem.

+That way it is easyier to figure out if it's a bug in pycrypto or in your code.

+cheers,

+//Lorenz
