Just a note: current versions of the free GNU compilers (both gfortran and
g95) work fine for Amber (at least in my hands). The code they generate is
not quite as fast as that from ifort, but that only becomes important when
doing long calculations.
My general recommendation for "new AMBER users" (which is what Mark is
suggesting as well) is to use gfortran, which is simple to install and
configure. If you later find that Amber suits your needs, and want to run
long simulations, then you can consider installing other compilers. At that
point, you will (a) have more experience, which often makes tracking down
problems easier; (b) have a reference working installation, so that you can
more easily check the new compiles.
Thanks to Mark for providing the detailed instructions.
