Minimal Install on iBook G3 (1 usb) - Install X/gnome , etc..?

[Gable Barber]

Hello all - 
I have successfully install Yellowdog Linux 3.0 on my iBook G3. I did
the minimal install, and am trying to get X, Gnome installed. I have
configured yum to use mirrors, and have installed XFree86 ( yum
install XFree86) . Is it possible to yum install gnome-desktop  ..? Ot
just yum install gnome ..something to get the "full" Gnome package
.....?

Thank you for any suggestions...
