+Emerge `x11-themes/gtk-engines`
+<!--more-->
+While the solution may seem trivial, I spent hours trying to figure it out since emerging `x11-libs/gtk+` will only be built with GTK3 support. Emerging the above package will rebuild it with GTK2 support, which the [wiki](https://wiki.gentoo.org/wiki/GTK#GTK-2_and_GTK-3) fails to state.
