Hi Raman,
I think it will be very difficult to get this installation to work with
these compilers. I'm assuming that you got the gfortran compiler from
hpc.sourceforge.net as a precompiled binary? I'm pretty sure that compiler
is buggy and doesn't work very well for amber.
My suggestion is to build the gcc-4.4 compiler suite with gfortran from
macports (or fink, but I have my reasons for preferring Macports, but that's
a different discussion). Also build gcc_select and use that to set the
gcc-4.4 and gfortran-4.4 as the default compilers. Then it should work just
fine.
If you want a step-by-step,
http://amberonmac.blogspot.com/ has a very
thorough walkthrough that should get it working by following the (maybe
simple?) recipe.
Good luck!
Jason
