The init script(s) provided in FILESDIR for net-dns/bind has a license of GPL-2 but GPL-2 isn't within the LICENSE variable of the ebuild(s): files/named.init-r11 has license line: # Distributed under the terms of the GNU General Public License v2 ... and is used by the following ebuilds: bind-9.8.1_p1.ebuild:LICENSE="as-is" bind-9.8.3_p1.ebuild:LICENSE="as-is" bind-9.9.1_p1.ebuild:LICENSE="as-is" There are two options here -- either LICENSE in the ebuilds should be appended with GPL-2 to cover the init script, or the init script should be relicensed so that it is covered by current LICENSE (this one is probably the preferred resolution). See also bug 425702 .
This has been fixed in 9.9.5.
