The ++local option isn't available for MPI builds. The charmrun script is
just a hack that calls mpirun, so forget it exists as well. Just run the
MPI-based pgm binary as you would any other MPI binary.

I have been able to install the 'net-linux' form by compiling the source code. To get a better performance I am trying to install the 'mpi-linux' version of NAMD. I am having some issues doing that and I have tried looking at the archive, but couldn't find a similar issue faced by other AMD 64 queries.
