glib-sharp will only get a new release with the new API that we need for 3.0 in a year or something. Instead of waiting a year before we can release something we now have our own internal copy of glib-sharp trunk that will be dropped once glib-sharp 3.0 is released. Everything is now compilable and working without any additional patches.
