The problem is the following lines:

--8<---------------cut here---------------start------------->8---
(load (concat "/usr/share/"
	      (if (boundp 'flavor) (symbol-name flavor)
	          "emacs")
            "/site-lisp/slime/slime-autoloads"))
--8<---------------cut here---------------end--------------->8---

The full output helps understanding the problem
=====

/u/s/emacs22/site-lisp/slime/slime-autoloads.el is not present yet, thus
the code I reported previously fails.

Loading /etc/emacs/site-start.d/50slime.el (source)...
Loading /usr/share/emacs22/site-lisp/slime/slime-autoloads.el (source)...
=====

At this point, /u/s/emacs22/site-lisp/slime/slime-autoloads.el is
present because we have already installed slime.

Note that /u/s/emacs/site-list/slime/slime-autoloads.el is *always*
present, which means one possible solution would be to always load that
instead.  This does not change anything WRT the current situation,
because /u/s/emacs22/site-listp/slime-autoloads.el is exactly the same
the slime package install.

However, while this would solve the problem, it is not the correct
solution, since what we want is to use the compiled elisp files, thus
we should replace the above with a simpler (require 'slime-autoloads).
The latter should be evaluated *only* if byte-compiled files have been
generated, or, witch is the same, if the slime package has been
completely installed through emacsen.

Suggestions are welcome :-)

Thx, bye,
Gismo / Luca
