ADD-READER-METHOD error

I got an error while trying to compile a clg from CVS today with SBCL 1.0.2 and also 1.0.3 on Ubuntu Linux (SBCL from sourceforge, not the Common Lisp Controller one available in Ubuntu).  I wish I could send a patch but I haven't been able to track down the cause yet:


STYLE-WARNING: redefining |gtk_window_position_get_type| in DEFUN
STYLE-WARNING: redefining |gtk_window_type_get_type| in DEFUN

I use the following:

(require :asdf)
(setf
 (logical-pathname-translations "clg")
 '(("**;*.*.*" "/home/lispnik/src/clg/**/")))
(push
 (translate-logical-pathname "clg:systems;")
 asdf:*central-registry*)
(asdf:oos 'asdf:load-op :gtk)
