As noted on this list several times - please don't follow those  
instructions, unfortunately they are not quite correct. The canonical  
source of information is CRAN and the R for Mac Developers' Page (the  
latter has correct instructions). If you have questions beyond that,  
please ask on this list first. Follow 3rd party instructions at your  
own peril.

You were in the wrong place at the wrong time ;). The network setup  
was changed on Monday and the nightly build didn't run 64-bit builds  
because of that. I have fixed the issue and re-started the build, so  
the full builds should be available shortly (you'll see that its safe  
if the "Date" fields of Leopard builds shows this afternoon or later  
(e.g. Jan 13 16:00 or later)). Thanks for reporting this.

Just to repeat the instructions - please use
curl -s http://r.research.att.com/R-2.8-branch-leopard- 
universal.tar.gz | sudo tar fvxz - -C /
and then pick the desired R GUIs from
