Fedora just has

polkit.addRule(function(action, subject) {
    if ((action.id == "org.freedesktop.packagekit.package-install" ||
         action.id == "org.freedesktop.packagekit.package-remove") &&
        subject.active == true && subject.local == true &&
        subject.isInGroup("wheel")) {
            return polkit.Result.YES;
    }
});

in /usr/share/polkit-1/rules.d/org.freedesktop.packagekit.rules. If you put the same file in there, it should work.
