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. (Here is the last
several lines from the ./configure output:

-L/usr/local/lib/gcc/i686-apple-darwin8/4.2.3

Has anyone successfully generated R on Mountain Lion?
