I tried running the ncdump utility built from netcdf-4.0.1.tar.gz, (using
"--enable-netcdf-4" in the configure step when building) and it worked OK
on the file you attached.  Maybe when you built netcdf-4.0.1, you just
used all the defaults without specifying "--enable-netcdf-4", in which
case you would not be able to read netCDF-4 files, only netCDF classic
and 64-bit offset files.  The file you attached was a netCDF-4 file.

For more information about the different format variants for netCDF,
