Couple of ebuild suggestions that I found useful: - Add [obex] USE dependency to bluez in RDEPEND (it is the default for bluez but somehow I had turned it off). - Apply the upstream patch from: https://git.gnome.org/browse/gnome-user-share/commit/?id=5bca8742e96bc5f3447be18e9c6ac5692cc3e3cd otherwise you may have to toggle bluetooth sharing in the applet on and off at least once to get obexd running as reported in the linked bug.
