Please read the R for Mac website (http://r.research.att.com/) - it  
has all the details (for some time now). Specifically go to


to get the recommended gfortran compiler (if you package contains  
Fortran code or you want to build your own R). This is also the  
compiler that is used for the R-2.5.0 alpha builds that are available  
from the same site and hopefully people are testing it by now ;). The  
HPC compiler doesn't work for us, because it's not universal.
