The path to mm-util is /usr/share/emacs/21.?/lisp/gnus/mm-util.el and
it's added to load-path by lisp/subdirs.el (not site-file.el) as in
the vanilla Emacs distribution.

The problem (or I would say "bug") is that SuSE[1] in fact require
some packages in site-start.el or files loaded by it:

,----[ site-lisp/site-start.el (wrapped long lines) ]
| ;; Load some package startups
| ;; --------------------------
| (let ((dir (directory-files "/usr/share/emacs/site-lisp/"
| 			    t "^suse-start-.*\\.el$")))
|      (while dir (load (car dir) nil t t) (setq dir (cdr dir))))
`----

The bug is that those require url:

,----[ site-lisp$ grep -e "require.*url" suse-start-*.el ]
| suse-start-url.el:(require 'url)
| suse-start-w3.el:(require 'url)
`----

AFAICS this is completely needlessly, as they only frob load-path to
include site-lisp/url/ or site-lisp/w3/. So, url requires url-var,
which requires mm-util:

,----[ site-lisp$ grep -e "mm-util" *.el */*.el ]
| url/url-vars.el:(require 'mm-util)
`----

A better solution (for SuSE) would be to use `subdirs.el' as the
vanilla Emacs distribution does. Maybe they would need to add some
auto-load statements somewhere.

For the SuSE-users, I would recommend:

1) Get rid of site-start.el and eventually replace it with a new file.

   # cd /usr/share/emacs/site-lisp
   # cp -p /usr/share/emacs/21.?/site-lisp/subdirs.el .
   # mv site-start.el SuSE-site-start.el

   # emacs site-start.el
   ... and add the stuff you really need (e.g. from SuSE-site-start.el).

2) Rename or remove:
   /etc/skel/.emacs
   /etc/skel/.gnu-emacs
   ~/.emacs
   ~/.gnu-emacs

   # emacs ~/.emacs
   ... and add the stuff you really need.

I've done this (or let's say something similar) with many SuSE- and
Emacs-versions up to SuSE 7.1. AFAICS, it still applies to SuSE 8.0.

Bye, Reiner.

[1] Not only SuSE; I've read about similar problems with Debian too.
