> you can derive a version of the cc-by work, eveb with no modifications. You just need to give it a different name and credit the original author. Then you can change the license to a compatible one. I suggest cc by sa since this adds GPL compatible copyleft. Changes on your version need to be relicened as ccbysa then while the original ccby version stays untouched.

Do you believe that it is needed to re-license it, I would prefer to 
leave the license untouched, and include it "as it is", if possible.
My impression now, after reading all the posts about this theme on the 
debian mailing list is, that they didn't make a difference between 
cc-by-sa or just cc-by. They just mention the cc-by-sa on the wikki 
page, because it is more restricted, but open enough.
Oh, what a hell, those license jungle. :-(
