Put it into the Collector - seems to be a bug.

I fear it will not be too easy.

   I looked at the code in "AccessControl.Permission".
   It is not easy. It would take me some time to understand
   what happens there.

   If you are lucky, then all base information is contained
   in declarations of the form:

      _<mangled_permission_name>_Permission= <role tuple>

If I had your problem, I would use "ZopeFind" to locate
all objects, look at all permission declarations that
have the form above and remove the role to be deleted.
As mentioned, permission mapping information may be hidden
in other attributes, too.
Then the algorithm above would not be complete.
