dependencies on gcc4

[Elias Pipping]

The gccs (both 3.3 and 4.0) that come with the
Developer Tools are not sufficient for building R.

They are only meant to (and able to) compile c,
c++, objc and objc++

According to the R FAQ [1], a fortran compiler is
required to build R, though.

The gcc40 port does include a fortran compiler,
whereas /usr/bin/gcc does not.
