Problem building PGP on NT

Hi, First question: Is this the appropriate place to go with this kind of question. If not, I apologize. Anyways here goes: I'm trying to build PGP, the MIT version under windows NT using Microsoft C++ version 4.0. The program builds after a few modifications to the makefile but cannot generate a RSA key. Everytime, I type pgp -kg and answer the required questions, pgp attempts to generate some primes and apparently fails. Anyone have a clue as to what the problem may be??? I know there is an executable of PGP for NT already made, I've used it. So I at least know it's possible to build on NT. Anyone else attempt a port to NT??? Thanks ahead of time, Max
