privoxy enabled ipv6 support by default, which can be disabled if needed. Currently gentoo ebuild don't support ipv6 USE flag. Let's implement it for situation where gentoo users need privoxy without ipv6 support. enabled/disabled FEATURE_IPV6_SUPPORT can be checked by requesting http://config.privoxy.org/show-status via own privoxy proxy. Reproducible: Always

Fixed in version 3.0.22 which is in tree now.
