He's right about needing a fast Math::BigInt library, the perl-only versions are too slow. It's been about 2 hrs and no results yet.
Actually, it runs in about 10 minutes with the perl-only version on my machine. The problem is, there's a bug in some versions of the pure perl BigInt module, and the L3 algorithm isn't guaranteed to terminate in that situation. Try the latest version from the author's web page.
