It appears that you linker can't find the Fortran entry-points in the
netCDF library.  What does the following command produce on your system:

    /usr/bin/nm -rg /d/span9/pascale/NETCDF/netcdf-3.4/lib/libnetcdf.a | grep 
nf_create

On my IRIX 6.5 system, the equivalent command produces the following:

    [57]    |         216|            |Proc    |ref=1             |Text     | 
fort-control.o:nf_create_

This indicates that the "fort-control.o" module in the netCDF library 
contains the entry-point "nf_create_" (which your linker didn't find in your
netCDF library).
