madwifi-ng conflicts

net-wireless/madwifi-ng-tools:0

  (net-wireless/madwifi-ng-tools-0.9.4.4180.20120502::calculate, binary scheduled for merge) conflicts with
    ~net-wireless/madwifi-ng-tools-0.9.4.4165.20110816 required by (net-wireless/madwifi-ng-0.9.4.4165.20110816::gentoo, ebuild scheduled for merge)

I don’t require madwifi. I have unmerged both the madwifi-ng-tools
and madwifi-ng packages yet the dependency is still there.

How to resolve the dependency or better yet remove madwifi all together?
