[R-SIG-Mac] rgl crashes after one successful draw on R.app

[Roger Koenker]

I doubt that this is helpful, but I get:

> rgl.open()
Reading symbols for shared libraries . done

Program received signal EXC_BAD_ACCESS, Could not access memory.

And the same thing happens if I just do the commands inside the function individually.  SessionInfo() below.
