In the kodi package there is a X use flag in REQUIRED_USE that is on by default. However if you turn it off you get: -- !!! Problem resolving dependencies for media-tv/kodi ... done! !!! The ebuild selected to satisfy "kodi" has unmet requirements. - media-tv/kodi-17.6-r2::gentoo USE="bluray css dbus dvd mysql nonfree samba sftp (system-ffmpeg) systemd udev upnp webserver xslt zeroconf -X -airplay -alsa -bluetooth -caps -cec -debug -gles -java -lcms -libressl -libusb -lirc -nfs -opengl -pulseaudio -test -udisks -upower -vaapi -vdpau" ABI_X86="(64)" PYTHON_TARGETS="-python2_7" The following REQUIRED_USE flag constraints are unsatisfied: python_targets_python2_7 any-of ( gles opengl ) The above constraints are a subset of the following complete expression: python_targets_python2_7 any-of ( gles opengl ) gles? ( X ) opengl? ( X ) udev? ( !libusb ) udisks? ( dbus ) upower? ( dbus ) -- If I turn python_targets_python2_7 on then I get: -- !!! Problem resolving dependencies for media-tv/kodi ... done! !!!

So effectively X is not optional (so shouldn't be a use flag?). Also in the ebuild the variable PYTHON_REQ_USE is being set but doesn't appear to be used anywhere. However the variable PYTHON_REQUIRED_USE is being accessed but doesn't appear to be set anywhere (at least not in the ebuild itself (which doesn't inherit any eclass)). I'm wondering if that is a typo and perhaps that is related to X being always required.

I'm wondering if that is a typo and perhaps that is related to X being always required. python-single-r1 uses PYTHON_REQ_USE and it sets PYTHON_REQUIRED_USE.

You seem to be right about the X use flag. I'll fix that. Thanks for pointing this out! Note that in Kodi 18 (currently unreleased, but there's a -9999 ebuild), you can use USE="-X" (you have to set exactly one of the X, wayland, gbm use flags).
