In this particular case of CDDE I believe that the author simply made a
mistake. That was, perhaps, his first project under GPL. He did not
realize that the GPL preamble and appendix were inseparable parts
of the GPL document. For instance, his project page on Freshmeat 
explicitely states that CDDE 0.2.0 is under GPL.
The fact that he did not change any of GPL terms and conditions
in his edited license and kept the name of the license intact
also shows this.

I am still waiting for his reply. If he does not answer, I think a
possible solution is to fork, assuming that the upstream is MIA and
then correcting his mistake.
