weston-launch: xkbcommon error

[christophe.jarry at ouvaton.org]

Hello,

I have built Wayland according to the instructions available on
http://wayland.freedesktop.org/building.html. Then, as a normal user (member of the group
weston-launch), I do:

    weston-launch

I obtain this error:

    xkbcommon: ERROR: failed to add default include path /usr/share/X11/xkb

Does anyone know where the problem come from?

Thanks,

Christophe
