I believe you're supposed to use the same compiler for compiling both 
the netCDF libraries and WRF. In my case, I used the Portland Group 
compiler in both cases, and it works fine. Could this be the problem?

Another possibility might be your NETCDF environment variable, which 
should be set to the parent directory of your netCDF libraries. (So, for 
example, if your libraries are in /usr/local/netcdf/lib, and your 
include files are in /usr/local/netcdf/include, NETCDF should be set to 
/usr/local/netcdf.)

Hope this helps,
Steve
