Yes, At this point I have more than 8 separate builds of HDF5/NetCDF-4
(4 compilers, each with MPICH2 and OpenMPI and 2 versions of both HDF5
and NetCDF-4 for some of the compilers). Perhaps I should build them
again with debugging since I can't seem to see the values of any of the
variables in those libraries with the debugger.
