[R-SIG-Mac] Which gfortran for Leopard?

Dear Simon,

As a subscriber to RootTalk I have just received the following mail:
http://root.cern.ch/root/roottalk/roottalk10/0122.html

As you see there are other Mac users of ROOT who do not want to use fink 
but another gfortran compiler.
I seems that besides gfortran from your website, the following gfortran 
can also be used:
http://www.macresearch.org/gfortran-leopard

My question now is:
Can gfortran from macresearch also be used to compile R 32 bit and 64 bit?

Best regards
Christian

>>>>>>>>>>>>>>>>> Thus my question is:

>>>>>>>>>>>>>>>> I would recommend using the Leopard gfortran 4.2.4 for
