Error occurs in emacs 23.1.1 (x86_64-mandrake-linux-gnu GTK+Version 2.20.0) when starting slime (M-x slime).
;; Error while compiling /home/cbc/lisp/slime/contrib/swank-asdf.lisp: ;; Your ASDF version is too old. ;; Please upgrade to ASDF2 and in your ~/.swank.lisp specify: ;; (defparameter swank::*asdf-directory* #p"/path/containing/asdf/")
My Fix: I got the new ASDF2 text from http://common-lisp.net/project/asdf/, renamed swank-asdf.lisp to Oldswank-asdf.lisp, put ASDF2 text into a (new) swank-asdf.lisp file.
