[netCDF #BXR-962926]: Installing NetCDF library with HDF4 support

It looks to me like when you built hdf4, you did not
specify --disable-netcdf when building hdf4 - despite what
you say below. You might look at the file ${H4DIR}/lib/libhdf4.settings
and look for the line (probably at the end) that looks like this:
   Support for netCDF API 2.3.2: XXX
where XXX is either yes or no.
