我犯了用 MacPorts 更新现有端口的错误——现在 slime 和 swank-clojure 不再起作用。clojure-jack-in在 emacs 中调用时收到以下消息：
Versions differ: 2011-04-16 (slime) vs. 20100404 (swank). Continue? (y or n)
输入y会调出粘液 REPL，但是当我尝试评估 REPL 中的表达式时，我收到另一条消息：
Not connected. Use `M-x slime' to start a Lisp.
这里发生了什么？
以下是我init.el文件的相关部分：
;; slime
(setq inferior-lisp-program "/opt/local/bin/sbcl")
(add-to-list 'load-path
"/opt/local/share/emacs/site-lisp/slime"
"/opt/local/share/emacs/site-lisp/slime/contrib")
(add-hook 'slime-repl-mode-hook
(defun clojure-mode-slime-font-lock()
(require 'clojure-mode)
(let (font-lock-mode)
(clojure-mode-font-lock-setup))))
(require 'slime)
(slime-setup '(slime-repl))
(eval-after-load "slime" '(slime-setup '(slime-fancy slime-banner)))
;; clojure
(add-to-list 'load-path
"~/.emacs.d/elpa/clojure-mode-el"
"~/.emacs.d/elpa/paredit-22")
(require 'clojure-mode)
(defun turn-on-paredit () (paredit-mode 1))
(add-hook 'clojure-mode-hook 'turn-on-paredit)
