Unknown option '-setnumber'

http://homerreid.github.io/scuff-em-documentation/examples/HalfSpaceLDOS/HalfSpaceLDOS/ I perform gmsh -2 -setnumber N 4 Square_N.geo -o Square.msh, but '-setnumber' is unknown.

jzh@jzh-virtual-machine:~/scuff-em-installation/share/scuff-em/examples/HalfSpaceLDOS$ gmsh -2 -setnumber N 4 Square_N.geo -o Square.msh

--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD 
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

Thank you in advance.

Perhaps you have an earlier version of gmsh installed? The -setnumber option works for me in my current installed version of gmsh, which is version 2.9.3.

% gmsh --version 
2.9.3

I update the version of gmsh, it works. Thank you!
