Seahorse 0.8 will not compile against gedit 2.14 and no USE flag exists to disable gedit plugin compilation. Seahorse will not find `pkg-config gedit-2.14` - fixed by ln -s /usr/lib/pkgconfig/gedit-2.14 /usr/lib/pkgconfig/gedit-2.6 Seahosr will not find gedit includes - #include <gedit/*> on my system needs to be $include <gedit-2.14/gedit/*>
gedit-2.14 is not in the portage tree. I added seahorse-0.8.1 the otherday which does compile a plugin for gedit-2.14 and it will be the version to use with gnome-2.14 when it is added to the portage tree.
