On my scratchboard, I've put some code that allows you to enter moves and checks if they are legal (only promotion and castling over threatened fields are not yet implemented). If I've got more time, maybe there will be a cpan-module for it soon.
If I remove it from my scratchpad, I'll either put it to CPAN or at least to my homepage, and update this message by putting a link here.

Best regards,
