License of x11-misc/trayer-srg seems to be wrong. See URL for more information. Reproducible: Always
Source code claims to be MIT but contains GPL code.
I don't see much of a problem there, since MIT is GPL compatible. So simply change the ebuilds to LICENSE="MIT GPL-2+" and be done.
Okay. I made pull request to fix this. https://github.com/gentoo/gentoo/pull/4057
This is now fixed. Please close the bug. commit 0c58f3b631642344a9608077eab463b16ff6f0c6 Author: Harri Nieminen <moikkis@gmail.com> Date: Wed Feb 22 17:55:49 2017 +0200 x11-misc/trayer-srg: Update license
