The whole thing is written in vala and I'm again not sure if the vala parts are done right, but as tarball includes generated sources, ebuild still works. While this might depend on ibus 1.4, I've chosen not to.
Created attachment 355046 [details] ebuild for the package I forgot to attach the actual ebuild.
Created attachment 380424 [details] ebuild for ibus-kkc 1.5.21 Like in libkkc-0.3.4, change in the libgee slot; due to that, minimal libkkc required is 0.3.4.
