Should be fixed with bumped ebuilds. Please see PR at #687636

[Comment 8 jannis 2019-12-15 17:28:24 UTC]

Likely caused by default "-Werror"-CFLAG that was previously used with qlcplus. Can you please retry with qlcplus-4.12.2? Thanks!

[Comment 9 jannis 2019-12-24 12:18:37 UTC]

Fixed with app-misc/qlcplus-4.12.2. Please re-open if problem persists. Happy Holidays :)
