error compiling panel - no colormap member

["Yo 'Ric Dude" <ericmit ix netcom com>]

Ok, I'm trying to get the whole gnome cvs thing compiled, 
and I cant get past the following error in gnome-core.

Having traced through a pile of header files, the problem 
seems to be that my version of gdk.h doesn't have the 
required colormap field in the GdkWindow structure.
I have gtk+-1.0.0, and gtk+-1.0.1.  Neither has the 
colormap field.  Which version of gtk is required now?
Maybe the FIXME: needs to be taken care of? =P
