Sometimes FreeBSD patch 3rd part products when import it
to src, but i can't confirm for this case, since it was imported
a long time ago.

I could make clamav port depend of zlib installed by ports when
FreeBSD is < 6.3, but i cannot commit this kind of changes to
ports tree because FreeBSD 6.2 is no longer supported since
May 31 2008, almost 2 years now.

Users are warned to upgrade to 6.4 at least, it will be supported
until November 2010.
