Try compiling just sander with the original parallel Machine file. Other
programs, like new2oldparm, are not parallel. Make sure that the LOADLIB
variable points to the correct mpich libraries on your machine. (If you are
unsure, look at what the mpif77 script is doing...) If you haven't done so,
be sure you can compile and run the MPI test suite itself. Try to see how
your setup differs from that at Stony Brook, described on the Amber Web
site.

...hope this helps...dac
