First a warning - please don't follow all "Matthew's instructions"  
unless you really know what you're doing. They are slightly misleading  
and most of the them are not necessary (and some are outright  
dangerous). If you think the instructions on http:// 
r.research.att.com/ are not sufficient, please say so!

As for the GUI, you have to compile 64-bit version of the GUI once you  
have 64-bit R installed. You can do so as follow (paste in the  
Terminal, you must have Xcode installed):

svn co https://svn.r-project.org/R-packages/trunk/Mac-GUI
# svn may ask you to accept ETH certificate here if run for the first  
time
cd Mac-GUI
xcodebuild -configuration Deployment64
open build/Deployment64

The last command will open the directory containing the newly built  
GUI in the Finder, so you can do whatever you please with it (replace  
the 32-bit, rename, copy to Applications, ...)

As for installing Leopard R, the simplest way is to paste this in the  
Terminal:

curl -s http://r.research.att.com/R-2.8-branch-leopard- 
universal.tar.gz \
| sudo tar fvxz - -C /

You don't need extra library paths for 64-bit packages, but you want  
to use type='source' in install.packages for 64-bit (as the site says).

Cheers,
Simon
