There's a problem...

Even if I skip byte-compilation of these files for emacs-snapshot, I
still add the directory /usr/share/emacs/site-lisp/emacs-goodies-el at
the end of the load-path.  But this is done too soon during startup and
this directory ends up shadowing the emacs-snapshot file
/usr/share/emacs/22.0.50/lisp/net/newsticker.elc

We need to be able to add to the load-path without shadowing files that
may or may not be present (i.e. present in emacs-snapshot but not in
emacs21).

Anyone have any bright ideas?
