Ah, that's a difficult question, a very difficult question. Experts
disagree, and no court has ruled.

The FSF says it's a derivative work, Larry Rosen (and I) say it's a

Neither the OSL nor the GPL nor the LGPL binds collective works to
reciprocity, everyone agrees on that. But:
God bless the King, I mean the Faith's Defender;
God bless (no harm in blessing) the Pretender.
But which Pretender is, and which is King,
God bless us all! --that's quite another thing.
--John Byrom (1773)
There is a similar dispute, though not so problematic, at the other end:
does mere compiling of source code create a derivative work, or is the
object code the original work in a different medium, as a paperback
book is the same work as a hardback original? Nobody knows the answer
to that either.
The reason it matters is that pretty much everyone agrees that a tarball
is a collective work, and if when compiled it is still a collective work,
then it is not derivative of any of the works contained in the tarball.
