R build needs a real FORTRAN in the PATH

[stephen@…]

The R configure script will eventually try to find a FORTRAN compiler named `fc' if no other FORTRAN compiler is available. However, on my Mac OS X 10.4.10 "Tiger" system, there is a script /usr/bin/fc which apparently just invokes the Bourne shell builtin of that name. The configuration fails with

checking how to get verbose linking output from fc... configure: WARNING: compilation failed

See `config.log' for more details.

I'm not sure what the right solution for MacPorts is, but for me installing the g95 port allowed R to build.

R currently has gcc42 and gcc43 variants, with gcc43 being the default; these install a fortran compiler, so that should solve this issue. Speak up if that's not the case.
