Ok, if you can't find libnetcdf_c++.so within the netcdf lib directory, then we 
have a few problems. In this situation, nc-config is your friend. First, let's 
make sure you are looking in the right place for netCDF:

nc-config --prefix

Now that we know where netCDF lives (or at least the one your account it able 
to see), let's see if it has c++ enabled:

nc-config --has-c++

Also, you will need to add -lnetcdf after -lnetcdf_c++ to your $(CSU)_LDLIBS 
flags in order to properly link to the netCDF library.

Let me know what you find with nc-config :-)

Cheers,

Sean
