I'm trying to build R on my MacBook Pro which is running Mac OS X 10.8.1 (Mountain Lion). I installed Xcode 4.4.1. I installed GNU Fortran 4.2.3 downloaded from the R project site. I downloaded the R 2.15.1 source. When I do a ./configure, I am told that Fortran isn't working.

I think you're simply missing -arch flags to your compilers, so you have mix of architectures - you have to configure all compilers with the same architecture (see FAQ). Cheers, Simon
