wrong. These are generated files that should be updated automagically by
ports whenever GDK loaders or GTK immodules respectivly are added.
As such, these files shouldn't live under /etc but under /var/db... and
they should be generated on package install instead of through funky
sed magic in the Makefile.
So now they are. :)
Oh and regen the PLIST, since, we're hacking the crap out of it anyway.
