Oh, I must have been looking in the wrong place for approval.

Common Public License Version 1.0
    This is a free software license but it is incompatible with the GPL.

    The Common Public License is incompatible with the GPL because it 
has various specific requirements that are not in the GPL.

    For example, it requires certain patent licenses be given that the 
GPL does not require. (We don't think those patent license requirements 
are inherently a bad idea, but nonetheless they are incompatible with 
the GNU GPL.)

12 Does the CPL allow me to take the Source Code for a Program licensed 
under it and include all or part of it in another program licensed under 
the GNU General Public License (GPL), Berkeley Software Distribution 
(BSD) license or other Open Source license?
No. Only the owner of software can decide whether and how to license it 
to others. Contributors to a Program licensed under the CPL understand 
that source code for the Program will be made available under the terms 
of the CPL. Unless you are the owner of the software or have received 
permission from the owner, you are not authorized to apply the terms of 
another license to the Program by including it in a program licensed 
under another Open Source license. By the way, the same answer applies 
if you want to include source code licensed under another Open Source 
license in a program licensed under the CPL.
