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.

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...]
