I do apologise for missing your report. I had a direct e-mail from Thomas Cech of SuSe Linux, and I believe this commit addresses your request: 21 Jan 2014; Tony Vroon <chainsaw@gentoo.org> -connman-1.15.ebuild, -connman-1.16.ebuild, -connman-1.17.ebuild, -connman-1.18.ebuild, +connman-1.20.ebuild, +connman-1.21.ebuild: Version bump. Ebuild changes by Tomas Cech of SuSe to properly install documentation and allow openconnect to be used. Removed old versions up to last stable.
