[Rd] RCmdr on Linux with R 2.0.0 over VNC can't use GLX

[Bob Kinney]

Hello,

I'm a admin over at Harvard University and I have quite a few users that
use R predominately over VNC.  In the past this has not been an issue,
but after upgrading to R 2.0.0 they can no longer use RCmdr over VNC. 
When trying to use the package, they see the following:

> library("Rcmdr")
Loading required package: tcltk
Loading required package: zoo
Loading required package: strucchange
Loading required package: sandwich
Loading required package: rgl
RGL: GLX extension missing on server
Error in firstlib(which.lib.loc, package) :
        error rgl_init
Segmentation fault (core dumped)

The same commands work fine when using a non-VNC display.  Is it at all
possible to modify RCmdr to not use GLX when it is unavailable?

Regards,
Bob
