Version 3.0.13 has been released. It's a "beta" version, however Gentoo (almost) always bumped ebuilds for each privoxy version regardless beta/stable status according Changelog. Thus I think we should add this fresh version to portage as well.
Created attachment 197241 [details, diff] ebuild for version 3.0.13 This ebuild removes ipv6 patch and USE flag because it's part of official release now. This ebuild provides automated tarball name switching ({stable,beta} suffix) by micro version number. (Even versions are stable, odd versions are beta.)
Fixed in cvs, thanks!
