[R] X11 not configured on linux RedHat 9

[Justin Fay]

I'm using Linux version 2.4.20-8smp (gcc version 3.2.2, RedHat 9). I 
installed R-1.7.1-1.src.rpm following INSTALL. However, no X11 device is 
found when I run R.
 > X11()
Error in X11() : X11 is not available

In the configuration, I found "checking for X... no"

How do I configure so that X11 device capability is installed?
