Yeah.  I don't think it is distributable, and therefore not DFSG-free.

While the copyright holder can certainly distribute obfuscated source
and no one can tell him not to, the GNU GPL by which the licensees
(i.e., we, and our users) are bound requires them to distribute source
in the "preferred form for modification", which is not available from
the copyright holder.  Licensees cannot meaningfully fulfill the
requirements of the GNU GPL, therefore they "may not distribute the
Software at all".

Non-distributable means non-free.  You should probably file a grave bug
against this package.  Feel free to quote this mail.
