I think you also need to reference the "include" directory if your "deform_1.f"
program has an "include netcdf.inc" statment in it, so depending on where you
installed netcdf, your command line should look something like:

  $ ifort -O3 -I/usr/include deform_1.f /usr/lib/libnetcdf.a -o deform

If you have a "use" staement referring to an installed netCDF module such as
netcdf.mod for the Fortran-90 interface, you will also need to indicate to
ifort where to find that, possible with a "-M" argument.
