See tracker bug 350792. virtual/dhcpc packages: net-misc/dhcp net-misc/dhcpcd net-misc/pump Please convert to a new-style virtual. Or, since it has only three providers and few dependencies, remove the virtual entirely.
In fact, only one package, namely net-wireless/wifi-radar, depends on the virtual. It could easily be changed to depend on "|| ( net-misc/dhcpcd net-misc/dhcp net-misc/pump )" instead. CCing maintainer. I'm going to punt the old-style virtual in one week from now.
Done.
