Please look at features2d USE flag - it is default and must be set, but it doesn't.
features2d USE flag is not disabled via /etc/portage:


> grep -R features2d /etc/portage/

sys-apps/portage-3.0.13::gentoo was built with the following:
USE="gentoo-dev (ipc) native-extensions xattr -apidoc -build -doc -rsync-verify (-selinux) -test" ABI_X86="(64)" PYTHON_TARGETS="python3_7 python3_8 (-pypy3) -python3_9"

Are you sure you don't have something else which may be disabling it?

Like usage of -*, or perhaps even a custom profile.

eigen is also a default flag

Please run: grep -r . /etc/portage/

Thanks! That was the cause of my issue. I asked at IRC first, but no one point me to this.

Sorry for noise!

FWIW, we don’t support that because of it negating defaults and so on.
