[R-SIG-Mac] rgl configure error: "missing required library GL"

[Davor Cubranic]

Thank you, that fixes it. 

I also noticed the following warning when installing 64-bit version of the package (the default, on OS X):

Sure enough, osx/osxgui.o is the only object file built for the 32-bit architecture:

I'm attaching the full log of configuring and building the package. I don't see osx/osxgui.o it being explicilty built, unlike the others.
