IANAL either. My concern is not compatibility between the licenses
themselves. Apache certainly allows the creation of derivative works
and as far as I can tell the BSD license is not incompatible with it.
I am more concerned with the wording of the contributor license which
requires contributors to assert that they are the copyright owner
(clearly in this case I would not be) and that their contributions
will be licensed under the BSD license.

That said I won't fret about it.
