this error message comes from Open MPI, not from Firefly.
Did you properly compiled your Open MPI binaries from the source
code? Maybe you just moved it form one system to another into a
different directory? Note, the second way does not work with Open MPI!
I'd suggest you to search the web for answer. E.g., look at the
OpenMPI web site which hosts Open MPI mailing lists archives.
