Cathy,

Apparently, the current netCDF/Perl package will work with the current netCDF-4 
package *if* the configure(1) script of the netCDF-4 package is the options 
"--disable-netcdf-4" and "--enable-shared".

According to Ed Hartnet (one of the netCDF-4 developers) use of the 
"--disable-netcdf-4" option would mean the following:

1. Such an installation would not be able to read or write netCDF-4/HDF5
files.

2. It would be able to read or write classic format or 64-bit offset format
files without difficulty.

3. If you don't need to read/write netCDF-4/HDF5 files, then building with
--disable-netcdf-4 is a good way to get the core library and tools. You
will still get the opendap client too.

Is this acceptable or do you need to access netCDF-4/HDF5 files using the 
netCDF/Perl package?
