Hi
Before Mpich installation i installed gfortran. But I have not installed g90 or g77 at all.
I have just reinstalled Mpich using enable g90modules flag, but mpif90 is no show.Do I really need g90 compiler for Amber10 parallel installation. Using gfortran I successfully installed serial Amber10 before.

If you ALSO don't have mpif77, then it's likely that your MPICH was compiled without any fortran support and you'll need to build an mpi that does. However, if the above command reveals a f90-compatible compiler, I.e. gfortran or ifort or something, you can simply replace mpif90 with mpif77 and compile that way.
