I don=E2=80=99t think so.  :-)

>From what I understand the problem is that we end up with the two
variants of gdk-pixbuf in the dependency graph, and it turns out that
it=E2=80=99s not the one we were hoping for that gets picked up.

The solution to this is to =E2=80=9Cdebug=E2=80=9D the dependency graph and=
 arrange
things so that the dependency graph of GTK+ includes only one variant of
gdk-pixbuf.  (It might be that it=E2=80=99s easier said than done, but we h=
ave
to try!)

WDYT?
