problem with libpixmap.so

[Michael M <lordvader eisa net au>]

Hi. I've just upgareded to Gnome 1.2, and I'm very happy with it. 
However, there seems to be a problem with the GTK themes. I built 
everything from the sources, and now, whenever I apply a gtk theme, some 
parts will have new dressing (namely the gnome panel, and parts of the 
control center), but the rest only get a colour update (whilst keeping 
the default widgets).
The closest I've gotten to pinning down the problem is this message 
which is printed whenever I start a gtk app:
Gtk-WARNING **: Unable to locate loadable module in module_path: 
"libpixmap.so",

That file is built by gtk engines. Since eveything else works, I am 
wondering what the problem is. Has anyone else tried out a themes Gnome 
1.2 sucessfully?
