is my work-in-progress branch. It currently breaks the contrib build as it detects variances in imports that we didn't care about before.

You can hotpatch an existing SBCL by C-c C-c'ing the DEFINE-CONDITION PACKAGE-VARIANCE-ERROR and the DEFUN UPDATE-PACKAGE-WITH-VARIANCE to try it out.

Please let me know if this is what you had in mind.
