How do I install xfce?

[Todd And Margo Chester]

Hi All,

I just installed the basic server option on a new server.  I am happily
setting at an init 3 command prompt.  I can contract the Internet
with wget and yum.

How do I install Xfce?

    yum groupinstall xfce

Always use to do the trick.  I think I am missing some repos.
Anyone know what I am doing wrong?

Many thanks,
