(That is not needed if you updated, and does not contain a Fortran 
compiler.)

The R-admin manual says

gfortran from http://cran.r-project.org/bin/macosx/tools/gfortran-4.2.3.pkg

which is not the same thing.

And note the compiler is invoked as gfortran-4.2, not gfortran, which 
may or may not be the same thing.

We really can't read the manuals for you.  If you use a binary build of 
R (on any platform), you have to use exactly the specified toolset.
