I'm just getting back from vacation today.  I know we have run linpack
here using mpiexec in the past, and don't recall any problem.

This sounds in general like you compiled hpl with the wrong mpi library,
compared to what mpiexec was expecting.  You can change the latter with
--comm=mpich-p4, for example.
