I think, this is questionable issue. You may compress GPLed executable
by commerical archiver - this not make derivative work. Exepacker is a kind
of archiver (with included unpacker), which doesn't relates to packed
contents (and it no neccessary for program), so, I suggest, this shouldn't
be called "derivative work".
As I understand, there is only one obstruction: if author od exepacker
doesn't allows free use its program, then is shouldn't be used freely.
Notwithstanding of packed program - GPLed or commerical.
PS: All above is only my IMHO, because I'm not a lawyer.
