Note that sander in version 9 supported the openMPI that was avaialable at the
time of the release. Since then, however, openMPI changed their way of doing
things. In particular, the openMPI mpif.h itself has inside it a fortran
'include' statement :-(
This means that you not only have to tell the preprocessor where "mpif.h" is,
but also have to tell the compiler what directories to search when processing
"include" statements.
Basically, this usually means replacing the "ifort" command with "mpif90"
in config.h.
...good luck...dac
