I think you need to make sure both the Fortran netCDF library and the C
netCDF library get searched, which requires 

  -lnetcdff -lnetcdf

instead of just 

  -lnetcdf

This is a change from earlier versions of netCDF, where the Fortran library
and C library were together in a single library archive.  The reasons for this
change were explained here:
