Well, no, there is no need to modify, and I would give credits, already
done on the project page, even if I didn't have upload the files to our
repository and will do in the about box as well, when I upload them.

I just was unsure what the license really mean, and if it is DFSGL
compatible. Now, after investigate some time in research, I know, that
the debain folks itself didn't know that for themselves, but the usual
practice is to accept cc-by since version 3.0 (2.5).
