*** Apparently Brew is "pretending" that GTK+ and several other things are installed (or at least it made links for them inside /usr/local/share/aclocal)...

(braden@BWM-Air):[~]$ brew upgrade gtk
Error: gtk+ not installed

*** I am not sure where it got the idea that it has GTK libs when it actually doesn't?
