Replying to ryandesign@…:

I mean the part that says:

gtk-osx-application-gtk2 is meant to be used only in a GTK quartz
development environment but your version of GTK does not
support quartz.  Please make sure that port gtk2 and all its
dependencies are built with variants +quartz and try again.

Since there was no reply, I'll assume that following the instructions shown in the error message fixed the problem.
