Could you indicate how it is that you have all the rights to distribute the code under the Perl 5 Artistic license?
This is a very legal question, I would not respond on it... seeing your responses might be used against you if you get anything 'wrong'. While it would be nice for your cool module to hop in an IBM product and have them make money on your code, it's not worth getting sued or contacted by an IBM lawyer.
I have seen pseudo-similar legal questions about whether a PAR compiled executable is legal to redistribute without an ActiveState license. I asked that the parties asking contact their lawyers to find out.
