You need to give ifort the flags it needs to know where netCDF was installed.  
For
example, if you installed netCDF in /usr/local, then you would need to use
something like

 $ ifort -I /usr/local/include simple_xy_wr.f90 -L /usr/local/lib -lnetcdf 
-lnetcdff -o simple_xy_wr

but I'm not sure what the correct ifort flags are.  For that you'll need to 
consult the ifort
documentation.

Right, these symbols were'nt find because you needed to tell ifort where to find
the libraries to link with, using the -L and -l flags, for example.

That error comes from that version of ifort not knowing to invoke the
Fortran preprocessor, fpp, to process ".F" files.  That version of ifort
only knew how to compile ".f" files.  This link explains that you need a 
later version of ifort that knows what to do with ".F" files:

I hope this helps.  We don't have ifort installed on our MacOS X test platform, 
so
we can't duplicate the problem or test that the current release works with that
platform combination.
