0.18 and 0.19 have a bug that will prevent library detection,
but other versions should be fine.
- * GTK+ (http://www.gtk.org/), version 2.16.0 or later. However
+ * GTK+ (http://www.gtk.org/), version 2.24.0 or later. However
it must be Gtk+ 2.something - The Gtk+-3.x series will NOT work!
* GtkSourceView (http://projects.gnome.org/gtksourceview/)
