I've got this error when I M-x slime for the first time:
LOAD: A file with name /usr/share/common-lisp/source/slime/swank-loader.lisp does not exist
I'm on Ubuntu 11.10 and have clisp installed through/as an Ubuntu package; otherwise, I'm using your latest (slime-2012-02-09). Any ideas what I've done wrong?
