title: SLIME not loading from Emacs
body: <p>I've recently updated SLIME from <code>package-list-packages</code> in Emacs. However, when I try to run it using <code>M-x slime</code>, I get this:</p>
  
  <pre><code>(progn (load "/home/koz/.emacs.d/elpa/slime-20140913.730/swank-loader.lisp" :verbose t) (funcall (read-from-string "swank-loader:init")) (funcall (read-from-string "swank:start-server") "/tmp/slime.3081"))
  
  * 
  ; loading #P"/home/koz/.emacs.d/elpa/slime-20140913.730/swank-loader.lisp"
  ;; 
  ;; Error while compiling /home/koz/.emacs.d/elpa/slime-20140913.730/swank/backend.lisp:
  ;;   Failed to find the TRUENAME of /home/koz/.emacs.d/elpa/slime-20140913.730/swank/backend.lisp:
  ;;     No such file or directory
  ;; Aborting.
  ;; * 
  </code></pre>
  
  <p>I still have a REPL afterwards, but I think this is very strange, and I'd like to know what's going on and why.</p>
