Presumably, these works licensed solely under the MPL or NPL are not derived works of a work licensed solely under the GPL. > [T]he thing at stake is the use of OpenSSL or Cryptlib[1] in the > Caudium[2] project.

Cryptlib itself has it's own copyleft which on the face seems to be GPL compatible.

What you need to do is file an ITP, then bring the texts of the licenses themselves so they can be analyzed by -legal for their DFSG Freeness. Then, once we know that the licenses themselves are DFSG Free, indicate which code is a derivative work of what, so we can examine the compatibility of the licenses.
