color-moccur.elを
(require 'color-moccur)
すると、下記メッセージが出てしまうのですがどう対処すればいいでしょうか？


ad-handle-definition: `ibuffer-do-occur' got redefined [2 times]
ad-handle-definition: `moccur-quit' got redefined
ad-handle-definition: `moccur-mode' got redefined
ad-handle-definition: `moccur-grep-mode' got redefined
ad-handle-definition: `moccur-quit' got redefined

よろしくお願いします。
