Plese, update Zukitwo in portage to the latest version. Maybe the x11-themes/zukitwo package could be replaced by a x11-themes/zuki-themes, as there are other themes developed together with Zukitwo. See https://github.com/lassekongo83/zuki-themes
I've recently updated to 3.14 and the currently provided version of zukitwo in portage starts to have lots of issues. Even this requested bump would be out of date. There already is a 2014.10.22 version out. Bump please!
