*** Bug 504416 has been marked as a duplicate of this bug. ***
I've just committed net-dns/djbdns-1.05-r29 which fixes everything on my todo list. Once that's stabilized, the old revisions (which use the *-setup scripts) can be removed.
Fixed by removing all versions that used the setup scripts: 05 Sep 2014; Michael Orlitzky <mjo@gentoo.org> -djbdns-1.05-r26.ebuild, -djbdns-1.05-r27.ebuild, -djbdns-1.05-r28.ebuild: Remove old versions, fixing bug #504414 in the process.
