Allegro 8.1 Express + Emacs (slime): CLC Error

Hello Everybody,

I recently installed the acl express edition as described in franz's
installation.htm. I installed all patches via (sys:update-allegro) at the alisp
REPL. After that I ran the update.sh script to rebuild alisp.dxl.

Now, when I run slime inside Emacs (with inferior-lisp = alisp in .emacs), the
swank loader signals an error message 'Error: "Package "CLC" not found"'.
Googling revealed: It has to be the common-lisp-controller package. 

Some more googling and experimenting showed that this error occured in places
where debian and non debian packages were mixed. I am running Ubuntu 8.04. The
problem seems to be the allegro lisp image, since slime + sbcl/clisp/cmucl all
work (.deb packages).

Hints or ideas are very much appreciated! Thanks in advance.

cheers
