Regarding PATH and R.app. It is a well-known issue on OS X that R.app
does not inherit the environment variables set in the shell (for
example in ~/.profile or ~/.bashrc).
For example, it is complete standard that you get different output from
# echo $PATH
and
R> Sys.getenv("PATH")
The easiest way to fix this is to set the environment variable using
the ~/.Rprofile and set it for example by
Sys.setenv(PATH = "SOMETHING")
It can also be fixed by editing environment.plist (do a Google search
for instructions).

David,
I did notice in your log.txt file the following message:
ld warning: in /usr/local/lib/libfreetype.dylib, missing required
architecture x86_64 in file
It seems a bit far fetched for the missing symbol to come from
that library though (but this is a
JavaScripter/pythoneer talking :-).
I think it probably did -- the FT symbols are FreeType, used by rgl
to draw nice fonts.
But I don't know how to fix this, other than configuring without
Freetype (and so without nice fonts).

As I normally work on R-2.9, I just went back to R-2.8.1 and tried
the terminal procedure.
Got the rgl examples running without problems. So that is not the
cause of the error message either.
I also noticed you are using the latest rgl from R-Forge (83-751),
while I was using 83-3.
Both versions work on my system.
If someone could help out where _FT_Attach_File comes from ...

Tried that method:

David,
On my system libpng-config and xmkmf are in /usr/X11/bin, as on
your system.
Adding /usr/X11/bin to my path did not help. I think /usr/X11R6
is just a link back to /usr/X11.
Did you try the terminal suggestion?
Download rgl_0.83-3.tar.gz from CRAN, then in a terminal
Robs-Intel:~ rob$ pwd
/Users/rob
Robs-Intel:~ rob$ cd Downloads/ # To wherever the
rgl.....tar.gz got stored
Robs-Intel:Downloads rob$ ls
Cappuccino_Developer_Tools.pkg
Changes.app
Fluid_0.9.6.zip
iphone_sdk_for_iphone_os_2.2.19m2621afinal.dmg
rgl_0.83-3.tar.gz
...
Robs-Intel:Downloads rob$ R_ARCH=/x86_64 R CMD INSTALL --

I know, it is not the ultimate solution, but it might help to
know this works on your system.
