To see if this is the problem, try moving the (define-protocol-class design ()) in protocol-classes.lisp to above (define-protocol-class region (design)) in the same file.
Doing this fixes the problem. So I guess it's a problem with forward referenced classes in CMUCL and
older versions of
SBCL.
Feel free to trawl SBCL CVS to find the patch, and port it to your favourite Lisp implementation.
