I am attempting to install rgl from source within a freshly installed  
R 2.9.1(Patched) from the att.research site.
I am getting this warning at the end of the compilation process:

g++-4.2 -arch x86_64 -dynamiclib -Wl,-headerpad_max_install_names -

ld warning: in /usr/local/lib/libfreetype.dylib, missing required  
architecture x86_64 in file

And as a consequence am unable to load when running in the 64bit GUI

 > library(rgl)
Error in dyn.load(file, DLLpath = DLLpath, ...) :
   unable to load shared library '/Library/Frameworks/R.framework/ 
Resources/library/rgl/libs/x86_64/rgl.so':

   Expected in: dynamic lookup

In addition: Warning message:

Resources/library/",  :
   installation of package 'RGtk2' had non-zero exit status
Error : .onLoad failed in 'loadNamespace' for 'rgl'

I understand this is probably an X11 question rather than an R  
question, but I don't really know where to pose such questions.  I am  
hoping someone has some advice about how to repair or replace  
libfreetype with one that supports the 64 bit architecture? Or perhaps  
some advice about the best place to pose UNIX fixing problems?
