As gtk2 is on the way out, it would be nice if pinentry would allow gtk3 (pinentry-gnome3) to be compiled without needing gnome-keyring.
Only an ebuild change is necessary. I've tested the attached patch and it works for me.

Fixed USE flag bug in patch
I would just USE=gtk for that, without introducing dead flags.

Here I agree, lets just put it as the gtk USE and disable gtk2 pinentry at all as being EOL.
pinentry-gnome3 is now built upon the USE=gtk.
