I'm not sure which gui toolkit uses emacs (I never looked at the source
code, even if I do, it won't help me much), but for me works fine on f21
with gnome, also when you check about emacs it says 
'GNU Emacs 24.3.1 (x86_64-redhat-linux-gnu, GTK+ Version 3.14.0)'
so it does use gtk3 for sometihng. I think the version listed there is
one which was "present" while building/linking...
