Is there a separate library installed in /usr/local/gfortran/lib/
named libnetcdff.a (note the double "ff")?  If so, you need to use

  -L/usr/local/gfortran/lib -lnetcdff -lnetcdf

to link with both the separate Fortran library and C library.

Also, if you installed nc-config along with the other netCDF utilities
like ncgen and ncdump, you should look at the output from

  nc_config --flibs

which will show how Fortrna programs should be linked with your
installation.

If none of these solve the problem, please let us know ...
