Why don't you email ActiveState? I would direct this question directly to them and not this forum. PAR is a free alternative to some of the commercially sold tools ActiveState sells, namely PDK (PerlDevKit), so I can see them adding terms to their copyright that would protect their work from being included in works distributed externally (presumbably for a profit). If you are not going to keep it in your organzation, then you can always purchase PDK Deployment Tools and use PerlApp to build your app, else, if you want to save the $145, build your own Perl distribution and use PAR with that.
