Yes - gfortran in on the executable path. From the errors it appears that the Fortran library (presumably installed with gfortran) is not available to the linker? I presume that LD_LIBRARY_PATH needs an additional path for the Fortran stuff, but I can't seem to figure out where the gfortran library lives…

Being inexperienced with Fortran, I'm looking for some help with how to proceed I am using gcc and g++ version 4.5 - is this correct? Can anyone tell me which version of gcc works best? Or, perhaps I have some kind of path information for the Fortran libraries missing - any pointers on which environment variables are necessary would be great. Thanks!
