It looks like you're using mpiexec provided from OSC.  You'll need to
update this with 0.84 when it is released or use their svn trunk
version until then.

You can find their main webpage is located at
http://www.osc.edu/~pw/mpiexec/index.php.  You can use 'svn co
http://svn.osc.edu/repos/mpiexec/trunk mpiexec' to check out their
trunk.
