That only applies if using xorg-modular. You will need to source
$GRIMOIRE/FUNCTIONS and use check_if_xorg_modular_libs or
check_if_xorg_modular_server, depending on if OpenSSH needs X11-LIBS or
X11-SERVER for this functionality.
If openssh only needs xauth and not all of X11-LIBS or X11-SERVER I'm not
sure
how we should handle this.
