Can't find file "xfree86" for keycodes include

["Igor B." <amzuk@land.ru>]

ARD keymap compiler (xkbcomp) reports:
> Error:            Can't find file "xfree86" for keycodes include

>                   Abandoning keycodes file "default"
Errors from xkbcomp are not fatal to the X server
Couldn't load XKB keymap, falling back to pre-XKB keymap

подскажите как это вылечить?
muchos gracias!
Igor.
