I'm afraid www/squid still can't be used for some configurations. For example, with ntlm or kerberos authentication. There is even a ticket in squid's bugzilla about that. http://bugs.squid-cache.org/show_bug.cgi?id=3997 While www/squid33 doesn't have such problems. So I plead, please, don't delete www/squid33 from ports tree so soon. Extend the expiration date.
