Just a heads up, I'm note sure who maintains the SARE Ratware rules, but itIt has no appointed maintainer, but I'm the one who has taken up the job of cleaning up the set.
looks like that's the last ruleset that still has lint errors under 3.0.
All the others seem to have been updated.
A fixed set should be available shortly, but that will be the last version of sare_ratware. All rules are moving to either sare_html, sare_random, sare_headers or sare_redirect.
