If rgl is using non-standard features in its makefiles, let me know what 
they are.  I use GNU make, so it's easy for GNUisms to slip into it.

We already have special handling for X11 on the Mac.  I don't know why 
yours isn't working, but it's pretty well-known that homebrew breaks the 
usual R build system, so I'd blame it on that.  If you are using 
homebrew, you should be prepared to manually configure rgl.  Or you can 
send me a patch to rgl's configure.ac that works around the differences, 
and I'll try it out.
