I see.  I can reproduce the error, even with the recent McCLIM CVS
version.

AFAIK CLISP support in McCLIM is somewhat tentative, McCLIM is usually
run with SBCL or CMUCL.  I'd suggest to report the problem to the McCLIM
development list ( mcclim-devel@common-lisp.net or
gmane.lisp.mcclim.devel on GMANE) and to try to work on fixing it with
the McCLIM developers directly.
