Seems like the ebuild passes unknown options to configure Reproducible: Always Steps to Reproduce: 1. Just emerge knot Actual Results: configure complains about unknown options configure: WARNING: unrecognized options: --disable-debug, --disable-debuglevel Fixing the ebuild should be straight forward, I guess. As far as I can tell knot does not have any debug related configure options (anymore).
I opened a pull request fixing this issue along with the version bump: https://github.com/gentoo/gentoo/pull/4329
