Comment (by wdc@…):

 It turns out that in 2011, the gnome folks actually coded and checked in a
 change that switch us from ige-mac-integration to gtk-osx-application, but
 the change
 was never released.  I took the diffs from the commit, and modified the
 Portfile to use it. It works!  I have attached the relevant revised
 Portfile and diff.
 Note that we stop using a patch to gtksourceview-i18n.c because the diff
 goes against upstream source.
