This is in the CLX layer. try running the clx demo to see if it works,
to fix that

I got the README example working with current sbcl. I'm not using or
quicklisp/asdf and when I do (set-difference *features* *) with your
features, I see these features in my lisp which are not in your lisp,
once mcclim and its dependencies are loaded.

Apparently you are running a 32bit lisp, clx is of course expected to
work with 32bit lisps but the problem is likely there if you are on a
64bit machine, better check try to run the clx demo
