missing XKB rules file

[Stevan Tiefert]

Hello list,

I am getting a warning message during configuration of X.Org under FreeBSD
5.3:

XKB rules file '/usr/X11R6/lib/X11/xkb/rules/' not found
Keyboard XKB options will be set to default values.
Press enter to continue, or ctrl-c to abort.

I need the german XKB rules file and I think that I have not installed an
important package, but which one???

With regards
Stevan Tiefert
