[Wien] Segfault in lapw1_mpi (SL_INIT)

[Laurence Marks]

Good.

Be aware that openmpi does not pass environmental parameters unless
you force it to, so you may need to include these in the mpirun call.
There can also be some other subtle issues, and some of the utilities
in SRC_mpiutil (unsupported goodies) may help.
