[CentOS] CentOS6.4 and Apple keyboard

I have just installed (with kikstart) centOS6.4 on a PC which was 
previously running OpenSUSE (11.x).
This PC has an apple keyboard and I'm unable to setup this keyboard.
In .xsession-errors I get this messages :

Error:            No Symbols named "latin9" in the include file 
"macintosh_vndr/fr"
                   Exiting
                   Abandoning symbols file "(null)"

** (gnome-settings-daemon:8160): WARNING **: Could not activate the XKB 
configuration

Google found on a RedHat forum that it seams to be an old known bug but 
do not find any update or workaround.
I've several PC using Apple keyboards as users have also Apple laptops 
and they do not want to work with two different keyboards.

Thanks for your help or advices.
