You have IPv6 disabled in your system somehow.

Squid opens IPv4/IPv6 hybrid sockets to receive and send both v4 and v6
traffic in one socket for simplicity and ease of transition. If that fails
like in your case it falls back to IPv4-only sockets.

I recommend re-enabling IPv6 socket capability in your OS.

If you have OpenBSD or MacOSX they do not support these hybrid socket
features at all. I'm still working on getting support for their
'split-stack'. So they will work very slightly better for now with IPv6
disabled in Squid.
