[netCDF #JHU-572616]: "SD" Errors

Make sure you're also using gcc -m64 when building netCDF, after building HDF4 
and HDF5.

Also, you can use the "file" command on dynamic libraries (that have a ".dylib" 
extension) and
on object files (that have a ".o" extension) as well as on executables, to see 
what architecture 
they are built for.  For example, 

  $ file /usr/local/lib/libnetcdf.7.dylib
  /usr/local/lib/libnetcdf.7.dylib: Mach-O dynamically linked shared library 
i386
  $ file /usr/local/lib/libhdf5.7.dylib
  /usr/local/lib/libhdf5.7.dylib: Mach-O dynamically linked shared library i386
  $ file /usr/local/bin/ncdump
  /usr/local/bin/ncdump: Mach-O executable i386

so on my system, those would all be for i386, a 32-bit architecture.
