but, indeed I do tell my application where to look for the libraries,
with environment variables like LD_LIBRARY_PATH. and this is a
tried-and-true way of telling the dynamic linker where to locate shared
objects.

OTOH, it seems GTK+ is hard-coding locations into its libs about other
resources. by now, I found that the GDK pixmap module file location can
be overriden by the GDK_PIXBUF_MODULE_FILE environment varabile, see
http://developer.gnome.org/doc/API/2.4/gtk/gtk-running.html

but, I bumped into a second problem - pango seems to do the same wierd
thing of hard-coding paths and relying on them. so far, I have not found
a way to override the hard-coded location it uses for the pango.modules
file :(
