Hi.  I just found out that the zlib-1.2.8-2 breaks clamav.  A log of the
output of the "sigtool" commmand from clamav is attached.  It's using
gzread() to read the compressed signature databases, and the format of
the data returned has apparently changed between zlib 1.2.8-1 and
1.2.8-2.  This should be fixed ASAP.

Thanks,
Mike
