Created attachment 533914 [details] complete build of gnome-control-center
I also had this problem and think it is caused by inconsistent use of the "wayland" use flag. Looking at the code, it looks like the missing function is called inside a "#ifdef WAYLAND" block. I was compiling gnome-control-center with "-wayland" but some of the dependencies had been compiled with "wayland". When I removed the following lines from my package.use: x11-libs/gtk+ wayland media-libs/clutter-gtk wayland >=media-libs/cogl-1.22.2 wayland >=media-libs/clutter-1.26.2 wayland >=media-libs/mesa-17.1.5 wayland and recompiled all affected packages, then gnome-control-center now compiles. I had to recompile ibus manually to get the post_inst compile of gtk+ to complete.
3.26.2 has the same error.
