Something is catastrophically broken. This would happen if you attempted 
to move a gromacs installation, messed with some system libraries, or 
possibly moved a binary .tpr file between different machines. 
Re-generate a new .tpr file on the same machine you will run mdrun on. 
If you still have this problem, and there's no indication your 
simulation set-up is wrong somehow, you should re-install gromacs properly.

The fact that you get some steps to work actually suggests you've got a 
problem with how you're doing your simulation. You'd need to describe 
that to get any useful help, however.
