X11 missing? ... was Re: [R] rgl persp3d bounding box color problem.

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 :-).

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 ...

Rob

Tried that method:

The compilation proceeded without error and was reported:

However, in R refreshing the Package Manager and attempting to load  
rgl fails to load with this error report:

Error in dyn.load(file, DLLpath = DLLpath, ...) :

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

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