Given the above, can I leave gfortran to point to the GCC fortran? if I do not, julia throws a hissy fit every time I compile it, though I use and need R *much more than julia*, so I'd like to avoid R binaries of any sort having a hissy fit if gfortran points to something else than gfortran-4.2. Between R and julia I'm with R.
