AFAICT, the status is as follows:

 a) works licensed under the terms of CC-by-v3.0 seem to be currently
    accepted by FTP-masters as DFSG-free
 b) some people (mostly myself!) disagree with this conclusion and have
    explained their position repeatedly on this list and elsewhere, but
    (unfortunately!) failed to gain consensus

For further details, see [1] where I failed to persuade a package
maintainer that there's a problem with CC-by-v3.0, and also [2]
where I provide a summary of the situation.

My own personal conclusion is unchanged (since nobody has provided new
facts about CC licenses that convinced me to change my mind), but the
opinion that matters, as far as the Debian Project is concerned, is the
FTP-masters' one: they are the real decision-makers.

There are several licenses that meet the DFSG and are perfectly
suitable for non-executable works: my own recommendations are the Expat
license [3] and the GNU GPL v2 [4].

[4] http://www.gnu.org/licenses/gpl-2.0.txt

For non-executable works that complement executable ones (e.g.:
documentation for programs, images used by programs, and so forth) the
general recommendation is to adopt the same license for executable and
non-executable parts.

This is really appreciated, indeed.

 Need some pdebuild hook scripts?
