Howdy David!

Firstly, are you sure that you need to do parallel I/O? You don't need it to 
read netCDF data files, you only need it if you want to read them in parallel 
on a high performance computing system. If you just want to analyze or 
visualize existing netCDF data, you can do that in sequential (i.e. 
non-parallel) mode.

If you still want parallel, your build did turn on parallel I/O with the HDF5 
library. You can now do parallel I/O to netCDF-4/HDF5 files.

If you want to do parallel I/O to classic or 64-bit offset netCDF files, then 
you need to install the parallel-netcdf library from Argonne/Northwestern 
University, and include it's path in your CPPPFLAGS and LDFLAGS.

In addition, it's not necessary to use the --enable-parallel-netcdf 
--enable-fortran or --with-zlib options to configure. If you wish to test 
parallel I/O, you should rerun configure with the --enable-parallel-tests. Note 
that these tests attempt to launch parallel jobs with mpiexec. Your platform 
must support it for the tests to run.

Thanks,

Ed
