koffice needs to be rebuilt with libgs.so.8. Which I've 
done. Why does yum keep wanting to upgrade to the extras 
koffice?

One issue:  the installed koffice where built --target=i486 
( don't ask).

rpm -q koffice-core.i486
koffice-core-1.4.1-4

But, why would yum try to install an x86_64 set? Will it 
always try to install the preferred target if another target 
is installed?
