Hi Ed, this didn't seem to make any difference. config.h has this
alarming section:
/* if true, parallel netCDF-4 is in use */
#define USE_PARALLEL 1
/* if true, compile in parallel netCDF-4 based on MPI/IO */
/* #undef USE_PARALLEL_MPIO */
/* if true, compile in parallel netCDF-4 based on MPI/POSIX */
#define USE_PARALLEL_POSIX 1
When I take a closer look at config.log, the check for MPI-IO (POSIX)
succedds but the check for "real" MPI-IO fails:

I can build the HDF5 tests no problem, but the HDF5 tests aren't
trying to use the symbol "H5Pget_fapl_mpipo". Instead, they use
"H5Pget_fapl_mpiposix"

The preprocessor suggests that something somewhere is defining
MPI_Comm and MPI_Info to be ints before including mpi.h
Thanks for all the help. I bet we're pretty close!
