Which strongly suggests that the cause is one of the many possible binary modules (Math::BigInt::BitVect, Math::BigInt::Pari and Math::BigInt::GMP.) that can sit behind use bignum doesn't properly handle log.

If you could dump your %INC, maybe we could track down which one(s).

    On the other hand, works well on perl 5.12.1 on openSUSE 11.3.
    Update: paths added. I checked everything in the perl_repo, it's latest CPAN version available.
