zlib-1.2.8-2 breaks clamav

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
