[R-SIG-Mac] gfortran and gcc 4.2

[Kasper Daniel Hansen]

An issue that is somewhat related: I was surprised to see a gfortran  
in both /usr/local/bin and /usr/bin, probably because I both had  
installed gfortran-42.pkg and the gfortran that comes with R-2.7.0. I  
(based on nothing but expectations) was expecting to just have  
gfortran in /usr/local. Is there any "policy" regarding this?
