The GdkPixbuf *is* a private structure, so it's ok that the file is not
installed.  You reference a GdkPixbuf by its pointer, so you don't need
the actual structure layout.  How are you trying to use it?  Sounds like
you're trying to malloc() a GdkPixbuf or allocate it in the stack.  You
can't do these things.  A GdkPixbuf is a ref counted object, which you
create using functions like gdk_pixbuf_new().
