Hello, you're receiving this canned bug because the package in summary uses the flag -Werror during build, which transforms warnings in errors, and is prone to break software when new GCC releases are added to Gentoo. Please make sure your package does not use -Werror during build, so that it can be more future-proof for the new GCC releases. Thanks, Diego

Thanks Vadim. Why are you inheriting autotools?
Created attachment 184581 [details, diff] disable Werror You are right. AT some point a forgot to remove it. In fact eutils is not needed anymore as well.
Fixed. Thank you.
