You're just calling the same (incorrect) command again. You installed
"gmx_mpi" version 2018.4 but then your command uses "mdrun_mpi" instead.
Apparently you have version 5.1.2 (perhaps from a package manager, based on
the fact that it's installed in /usr/bin instead of /usr/local/gromacs/bin)
that is being found in your PATH.

If you've got multiple versions installed, either source GMXRC properly or
use full PATH information in your commands. Above all, use the right binary
name to start :)
