As you yourself note, the GNU GPL has no equivalent requirement. You can take a GPLed work and modify it, after changing its source form (such as translating a program from Python to C++, for instance): if the new source form requires some proprietary tools (such as a proprietary compiler, for instance), so be it. It's of course undesireable for a work to require proprietary tools in order to be modified (or even used), but I think that this should not be forbidden by its license. P.S.: Please do not reply to me and the list, as I didn't ask to be copied. I am a debian-legal subscriber, and I don't need to read replies twice.
