I guess I should have asked earlier if you have installed netCDF-4, without
using the --disable-netcdf-4 option.  To install netCDF-4 you would have
had to install hdf5 first, because netCDF-4 depends on it.  To determine
whether you have netCDF-4 installed, try running ncdump on the attached binary
file:

  ncdump -k test.nc

and verify that the output is

  netCDF-4 classic model

If instead you get

  test.nc4: NetCDF: Unknown file format

then you haven't installed netCDF-4, which is required for the netcdf-cxx4
software that depends on the C library for netCDF-4.
