Whew, glad that is fixed.

Okay, I see.  A related PBSpro oddity that should be easy to
fixup.

That's very good advice.  I'll make that change when it is
invoked directly with a path, like

    ./mpiexec
    ~/newsrc/mpiexec
    /usr/local/testing/bin/mpiexec

however if it is invoked via a PATH search, there's no POSIX way
to figure out what directory the executable came from.  So hopefully
the redir-helper lives in the same spot in the PATH.

I'll point you to another -pre release soon.
