[gradsusr] Grads 2.0.1 Compilation Problem

[Jennifer Adams]

Hi, Spencer -- 
You are correct, you must not have the right version of netcdf.h in your supplibs (or wherever your netcdf4 build is located). This is where NC_CHUNKED is defined: 

> grep NC_CHUNKED ~/supplibs/include/netcdf/netcdf.h 
#define NC_CHUNKED    0
