x11/libxkbcommon is also used by Wayland e.g., in x11-toolkits/gtk30.
libinput as used by Wayland doesn't support anything but evdev.
If one enabled evdev(4) on FreeBSD 11.* then Wayland may work after applying

Did you mean from binary packages? If someone builds xorg-server from
ports it's probably due to non-default options. However, the ports
framework doesn't support checking ports options set in other ports
e.g., dependencies.
