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

The issue is with package rgl, and we need to talk to the maintainer, John 
Fox (Cc:ed here)

John: I am having problems too.  On AMD64, rgl was flaky under Fedora Core 
2 and crashes everytime on FC3.  It also crashes on 32-bit FC3 using Xvfb.
Could you please make it optional: few users will actually want it in 
every session.
