Did you remember to do (slime-setup ‘(slime-fancy)) or (slime-setup 
‘(slime-repl)) in your .emacs?
I've been trying to get Clozure CCL to work with SLIME, and continue to 
run into numerous problems with more recent versions.
In the process of 
upgrading SLIME, I have more problems with older versions of SBCL and newer 
versions of SLIME.
None of these problems occurred with the repository 
versions of SLIME.
I have also had similar errors with other lisp 
implementations (older versions) that had worked: CLISP, GCL, CMUCL 
etc.
Here is my current system:
Ubuntu 9.10: Kernel Version 
2.6.28.19
Emacs 23
Slime: CVS source as of 3/7/10
Clozure CCL Version 
1.7-dev-r14664M-trunk
SBCL 1.0.29
Steps taken:
1. Purge from system 
repository versions of SLIME + SWANK. 
   SBCL 1.0.29 and CMUCL 
(Python 1.1) worked with these.
2. Install most recent version of SLIME, CCL, 
SBCL
Results:
Slime Message when CCL invoked:
; Warning: These 
Swank interfaces are

SLDB-BREAK-ON-RETURN SLDB-STEP-INTO SLDB-STEP-NEXT SLDB-STEP-OUT)
; While 
executing: SWANK-BACKEND::WARN-UNIMPLEMENTED-INTERFACES, in process

It then drops me down into Emacs inferior-lisp.

Again, Slime drops down into

Any ideas what needs to be done?
