[R] rgl installation problems

[E GCP]

Hi!

I'm new to R, but have worked with Splus before. I installed several 
packages in R (R-1.9.1) without problems, but when I try to install rgl 
(rgl_0.64-13.tar.gz). I get the following, and the package does not install. 
Any help would be greatly appreciated. I'm running R in redhat 9.

Thanks,
Enrique
