Problems with installing the rgl package

I am having the following problem while trying to install the rgl
package on R 2.7.0:

configure: error: missing required header GL/glu.h
ERROR: configuration failed for package 'rgl'
** Removing '/usr/lib/R/library/rgl'
** Restoring previous '/usr/lib/R/library/rgl'

The downloaded packages are in
       /tmp/RtmpRLEDta/downloaded_packages
Updating HTML index of packages in '.Library'
Warning message:
In install.packages(update[instlib == l, "Package"], l, contriburl =
contriburl,  :
 installation of package 'rgl' had non-zero exit status

Any ideas?

You don't indicate which version of Fedora/RH you are on, but you need to
install the libGLU headers, which for F9 are in:

 mesa-libGLU-devel-7.1-0.29.fc9.i386.rpm

So, as root, you'll likely need:

 yum install mesa-libGLU-devel

Once that is installed, you should be good to go unless you are also missing
other dependencies as well.
