in reply to Artistic License and porting

Well, from my understanding (see ESR's summary), if your copy is inclusive of the code in an Artistically-licensed code, then you can release modified binaries without restriction, and without needing to release the source. If you wish to release the source, you'll need to release the inclusive parts under the Artistic Licence.

If your code is not inclusive, then you don't need to do anything.

But of course, I'm not a lawyer.
