The following ebuilds are using a rather non-standard SRC_URI protocol specifier- net-mail/spampmd-2.11.ebuild net-mail/spampmd-2.11-r1.ebulid sys-apps/nictools-20030719.ebuild all use mirrors://gentoo instead of mirror://gentoo ; I asked carpaski about this, aparently it should be the latter instead of the former. They appear to work still, but are definitely non-standard- only these 3 use mirrors instead of mirror in the entire tree...
sys-apps/nictools is fixed (it's my package). spampd belongs to mkennedy. both are fixed now.
