I'm new to slime. I tried using it with this in my .emacs: (setq inferior-lisp-program "/sw/bin/clisp") ; Platform is Mac OS X (Panther). CLisp is 2.29-13. (add-to-list 'load-path (concat homedir "/el/slime")) (require 'slime) (add-hook 'lisp-mode-hook (lambda () (slime-mode t))) (add-hook 'inferior-lisp-mode-hook (lambda () (inferior-slime-mode t))) M-x slime RET produces: Compiling file /Users/gknauth/el/slime/swank.lisp ...
