 Starting from netCDF 4.1.1 netcdf has a new c++ interface. This can be
 build using:

  ./configure --enable-cxx-4 [plus other options]

 Can you add this option to the netCDF portfile.
 I think the following should be added:

 variant cxx-4 description {enable netCDF-4 c++ interface} {
     configure.args-delete   --disable-cxx-4
     configure.args-append   --enable-cxx-4
 }

 Or maybe it makes more sense to add it to the netcdf4 variant.
 For details about the new c++ interface, see:
