[CentOS] mysql-server installing...or not`

Hi all,

I've got a clean CentOS 5.1 install and need php/mysql support.  Seems 
mysql (client) is installed, but I need server, so I did

yum install mysql-server

and got the errors posted below.

Have I missed something or is there a problem with this package?  
(actually I should ask do I need this package - I believe I do, but I've 
been wrong before - as recently as today :) )
