The configure script probably has some legacy checks in
it from the plug-in template code. Like, it looks for
GTK libs (like gtk-config) which I don't think we need
to have installed since we don't use any GTK GUI stuff.
There might be other stuff that is not really necessary
for our use. We should make a list of stuff we suspect
we don't need, then agree on whether it should be taken
out of the configure script.
