Created attachment 265485 [details, diff] patch for ipv6 support in dev-libs/geoip ebuild GeoIP creator Maxmind has an ipv6 country database available for free, see http://www.maxmind.com/app/faq#ipv6 Attached is a patch against current in-tree ebuild net-lib/geoip-1.4.6 that adds the ipv6 USE flag, downloads the data file and installs it in the appropriate location.
