There's an important clue in the error message: you need to use Math::Bigint; (or use bigint;). But if you aren't already doing that, what do you mean by a "bigint number"?

Oh, I see; you perhaps are using the ancient decrepit perl4-ish bigint.pl; you are strongly advised to install a new version of Math::BigInt (which I believe includes a bigint.pm module also) which has scads of bug fixes and use it instead.

You also should be doing print $bignum->as_hex();; just calling it in void context doesn't do anything.
