epiphany-1.6.0 brings d-bus support with it. But currently there is no option within the masked package. Here is a corrected ebuild. epiphany-extensions-1.6.0 could not be compiled with the dbus-extension without having that in the epiphany-ebuild.

We aren't going to include dbus support at the moment because of the changing api in the latest dbus release. Dbus-0.3.x is going to be much more of a priority then dbus support in epiphany which nothing we offer will use.
You would not provide beagle or dashboard?
no we don't provide those, and aren't going to anytime soon.
