>> This was our priority and we have smoothed all the wrinkles as far as
>> I can see. Building current R from sources on Leopard works just
>> fine. You can build both R and the GUI in 32 and 64-bit, leveraging

>> including the GUI if you wish, such R runs on both PowerPC and Intel
>> Macs in both 32-bit and 64-bit mode. The r_arch names must be i386,
>> ppc, x86_64 and ppc64 for the framework to install correctly.

>> * Using CRAN Tiger R on Leopard

>> and as such should work with Leopard, the Apple installer apparently
>> breaks this. This is under investigation. Current work-around is to

it works if we change manually the mac os x version in the two conf  
files
/Library/Frameworks/R.framework/Resources/etc/i386/Makeconf
/Library/Frameworks/R.framework/Resources/etc/ppc/Makeconf
