building gtk+ 2.2.1 (png loader module)

[Felix Natter <fnatter gmx net>]

hi,

I am trying to compile gtk+ 2.2.1 (as part of GARNOME 0.21.0).  gtk+
compiles fine but it seems like gtk+ didn't build the png loader:
compiling libgnomeui fails with this error:

I tried 1. to run `gdk-pixbuf-query-modules' => no non-comment output and
2. look at PREFIX/etc/gtk-2.0/gdk-pixbuf modules (I don't remember the
exact name) => many loaders are mentioned along with .so-na
(but these files don't exist in PREFIX), but "png" is missing.

I configured with --with-libjpeg --with-libpng (or similar) + some 
GARNOME switches for paths.
