good. try:
-----
   make clean-all
   make mpi # (for example, or "make ubuntu", if you are using ubuntu)

and if there is a problem with the conventional build system, it may
be worth trying out compilation with CMake instead.
CMake has a larger degree of automation and thus should result in more
consistent behavior.

another thing to watch out for, that wasn't mentioned before, is
compilation errors. if "make" or "make mpi" or "make serial" fails,
then you won't get an updated executable.

The edip potential is now working.

Thanks,
Andrew and Axel.
