libglade2 and gtk2

[Dr. Edward Ajhar]

libglade2-2.0.1_2 installs an include file
/usr/local/include/glade/glade-xml.h that contains <gtk/gtkdata.h>
that does not exist in the gtk-2.2.1_1 port (in
/usr/X11R6/include/gtk-2.0/gtk).  (This file DOES exist in
gtk-1.2.10_9.)

The result is that libgnomecanvas-2.2.0.2 and libbonoboui-2.2.0.1_1
fail to build.  Other similar failures may follow.  My ports were
updated as of May 4 around 10 am EDT.  I'm running 4.8-RELEASE.

I'm not sure how this should be fixed, unless libglade2 needs gtk12.
