Jeff thanks for your help
I tried to link the compiler to the netcdf.mod file but it did not help
(before I had a link to that file in the compiling folder)
The massages I get are not from not seeing netcdf.mod
I did see people use the -I switch but did not understand where do they
point it to.
Thanks again

Yair:  You need to use pass ifort (or any fortran compiler) the location 
of 'netcdf.mod', via '-I/path/to/module' and the library via 
'-L/path/to/netcdf/library -lnetcdf'.
