Thanks for the report.  (I had responded earlier, but used gmane, and
cmucl's lists don't allow mail from gmane anymore for some unknown reason).

In any case, see also http://trac.common-lisp.net/cmucl/ticket/84

I'm surprised anyone is using clm anymore, and I rarely, if ever, check
to see if it works. If you don't mind, can you tell me what you use it
for? I'm just curious.
