To be honest I'm a bit confused by this because find-class-slot is exported by mutility, which is :used by cl-patterns.

But I think this should now be corrected in commit fa5257b , which changes find-class-slot to be called with the package prefix.

I'm getting an error after this update:

It looks like find-class-slot doesn't appear in mutility? ... according to my sbcl anyway

When I remove the mutility: from the call I get the original error in this thread.

I just tried one more thing and it appears to work.

mutility has to be loaded from my local-projects clone of the git repo rather than from quicklisp. Once i cloned the repo myself and used the local version this all works again.

Hmm, okay, then maybe 421fd7a will fix the problem since it just copypastes the function into cl-patterns instead. So in theory it should be impossible for the function not to be available if one has the current version of cl-patterns.

I'm assuming it's just needed for this version of the quicklisp dist, and once the next one is out the duplication can be undone.
