The init script(s) provided in FILESDIR for net-p2p/bittornado has a license of GPL-2 but GPL-2 isn't within the LICENSE variable of the ebuild(s): files/bttrack.rc has license line: # Distributed under the terms of the GNU General Public License v2 ... and is used by the following ebuilds: bittornado-0.3.18-r2.ebuild:LICENSE="MIT" 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 .
Added GPL-2 license to the ebuilds: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=f4ca864be0cfc8ed6b9b3e3248b3b62bd5b871af
