> where should I look for this to fix? Theo has the answer for that one - a bad meta rule somewhere.
Given that --lint seemingly didn't catch it, and this pure perl error is less than descriptive of the problem, once you find the rule in question, I think it deserves a Bugzilla entry for failure to check sufficiently for bad meta rules in lint. You will need to supply the bad meta rule in question, and possibly the rules it depends on. If you don't have a Bugzilla account I'll enter it for you. Loren
