Looks like you have written something like
    PARA_PREFIX=mpiexec -n 5
in your environment_variables file. This is incorrect because
PARA_PREFIX is only set to "mpiexec", then the shell interprets "-n 5"
as a command. When the value of PARA_PREFIX (or PARA_POSTFIX) isn't a
single word, you must quote it:
    PARA_PREFIX="mpiexec -n 5"
