Notice that you are putting mpich into /usr/local, which is not a
standard location. The "-mpi" flag of Amber's configure assumes that
needed mpi components will be in the user's path or a standard system
path.
The *simplest* approach is to go the the "Installation" tab at
ambermd.org, and follow the suggestion there, which is this:
sudo apt-get install mpich libmpich-dev

This is the "second simplest" solution. It keeps everything everything
related to MPI inside the AMBERHOME tree, so reduces the chance that you
would interfere with other MPI programs you might have on your machine.

This is not needed, but should not hurt, either. The Amber installation
routines build FFTW from source.

This is because FFTW configuration (using sources in the AMBERHOME tree)
could not find the mpi libraries. Maybe someone on the list knows the
trick to get fftw's configure script to look in /usr/local, but one of
the two solutions listed above is what we recommend.
....hope this helps....dac
