[CentOS] [Solved] XKB: Failed to compile keymap

Solved; that was quick. :-)

For other reasons, /tmp had incorrect permissions. Changing them with 
"chmod 1777 /tmp" solved the problem.

The hint was this post, 
https://www.centos.org/modules/newbb/viewtopic.php?topic_id=41813&forum=56 
, which described other symptoms I also had: "gconf-sanity-check-2 
exited with status 256", and "The configuration defaults for GNOME Power 
Manager have not been installed correctly".

Thanks to jeepster for his post.
