Apparently, I'm missing the "GL" library. But how can I install it? I searched
for it on the web and mainly found that the Mac should have Open GL already installed (?).
Are you sure you installed X11 and Xcode4?
I have no problem with the *configuration* on vanilla Lion. There is still an
issue in the rgl 0.92.798 code (opengl.hpp), though, it's including AGL/*
instead of OpenGL/* which fails (hence CC to Duncan), but that's at compilation
stage, not configuration.
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.

BTW: why don't you just use
install.packages("rgl")
that works on Lion as well...
Cheers,
Simon
[PS: while at it - I'm a bit confused about the current setup, though, since it
uses the (non-X11) OpenGL framework yet links X11; Also it crashes when GLX is
not supported (e.g. ssh tunneling). 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...]
Cheers,
Marius
