Attached is a clamav license incompatibility bug with libgmp from the 
debian lawyers.
clamav might be forced to link against an older libgmp.

The switch to LGPL3 came with gmp-4.2.2, so gmp-4.2.1 would be needed 
for clamav compatibility.
But prev is gmp-4.2.3-1, so we might need a new gmp-compat package based 
on gmp-4.2.1.
Or clamav will decide to step up to GPL3

As I understand the issue, the problem is that the GPLv2 does not allow
for the extra restrictions imposed by the LGPLv3, and this is what make
the two licenses incompatible (i.e., the problem is solely in clamav's
court, not GMP's).

So, I think that if the clamav team could make a public license
excemption for this linking, the problems for distributors goes away.
It would be great if it was in the licensing statement in the release,
but failing that, a mail to the mailing list would probably be enough
for me to convince our archive administrators that it's ok.  This of
course assumes that the clamav team holds all the copyright for the code
that links GMP, which, given that the #include gmp.h is in the library,
might be slightly difficult.

If you guys don't have the copyright, or can't grant the excemption for
other reasons, distributors like myself will most likely have to build
without gmp going forward, which seem unfortunate.

Cheers,
