Well apparently not with win32 5.6 : 

#!perl
use strict ;
use warnings;
my $bignum = Math::BigInt->new('1111111111111111111111111');
$bignum->as_hex();
print $bignum ;

[download]

gives : 

Can't locate object method "new" via package "Math::BigInt" (perhaps y
+ou forgot to load "Math::BigInt"?) at t.pl line 4.

as_hex is not in the doc, either, but i indeed saw it with 5.8
