I have tried running SLIME (latest CVS sources) with CMUCL Snapshot 2005-09 (19B) under Slackware Linux 10.0 with GNU Emacs 21.3.2. when I issue the 'M-x slime' command after removing all fasl files in ~/.slime, I get the build error shown in the included transcript. CMUCL Snapshot 2005-08 works fine with the same SLIME sources, so the problem may be CMUCL related.

Here is my ~/.swank.lisp

(setf (cdr (assoc 'swank::*print-pretty* swank:*sldb-printer-bindings*)) t)

(load "/home/paolo/src/slime/present")

By the way, since I seem to understand that slime-present.lisp is not compiled by default, what is the recommended way of loading it from SLIME for all sessions? I manually compile it after getting new versions of SLIME, and load it from ~/.swank.lisp.
