I can't build on MacOS these days either.  The history is that at one 
point the R.app GUI worked better with the AGL code, while the command 
line version needed X11.  So it built separate shared libraries to be 
loaded depending on what it saw at package load time (I think rgl.* is 
for X11, aglrgl.* is for AGL).  I haven't kept up with Apple's 
rearrangements, so I don't know what is currently needed, and am 
unlikely to have the time to figure it out.

However, if someone who does know what's going on sends me a patch that 
doesn't obviously break something else, I'd be happy to commit it.

I remember that at some point in the past it was building native and X11 versions but what is left is some mix of both...]
