I submitted an ebuild for kde-misc/rsibreak-0.5.0 (see https://bugs.gentoo.org/show_bug.cgi?id=124174) which is now in portage, but only keyworded as amd64. I'm running a x86 arch, and it work well, so please add the x86 (or ~x86, of course) keyword to that ebuild.
It's working fine here also (~x86).
