Ah yes, you are right. Aporia is GTK2, so I guess it copy highlighting files not to /usr/share/gtksourceview-3.0/language-specs/
So I have to fix the NEd documentation. Maybe it is gtksourceview-2.0 for Aporia. Does nimble install aporia works for you without root rights? I have just asked about that on gtk mailing list, but do not really expect a reply...
