Dear List,
Please forgive the basic nature of this question.  I have looked for  
help on the list but have not been able to solve my problem.

I am trying to install the 64-bit version of R 2.8.1 on my machine, it  
is an iMac with the following configuration
Model Name:	iMac
   Model Identifier:	iMac8,1
   Processor Name:	Intel Core 2 Duo
   Processor Speed:	2.66 GHz
   Number Of Processors:	1
   Total Number Of Cores:	2
   L2 Cache:	6 MB
   Memory:	4 GB
   Bus Speed:	1.07 GHz
   Boot ROM Version:	IM81.00C1.B00
   SMC Version:	1.29f1

I am using the instructions on how to install the 64 bit build from:
I installed the R-2.8.1.dmg file from CRAN, then downloaded the 64 bit  
nightly build for Leopard from
I then replaced the R.Framework folder on my machine with the one  
generated from the nightly build.

However, when I try to run the 64 bit version from the terminal using:
R --arch=x86_64
I get
/usr/bin/R: line 206: /Library/Frameworks/R.framework/Resources/etc/ 
x86_64/ldpaths: No such file or directory

Any ideas would be most appreciated.
