The problem seems to be that the Fortran-77 interface is missing from
the netCDF library:

> Making `test' in directory /users/nala/netcdf-3.5.1-beta13/src/nf_test
...
>       xlf -q64 -o nf_test   test_get.o         test_put.o      nf_error.o

...

I note from your "make" output that the Fortran-77 interface modules
do not appear to have been added to the netCDF library:

> Making `all' in directory /users/nala/netcdf-3.5.1-beta13/src/fortran
> 
>       xlc -q64 -c -qstrict -qarch=3Dpwr3 -qtune=3Dpwr3 -I../libsrc  -DNDEBUG 
> for=t-attio.c
...
> Target "all" is up to date.
> 
> Returning to directory /users/nala/netcdf-3.5.1-beta13/src

There should have been an invocation of the ar(1) utility at the end of
the above output in order to add the Fortran-77 interface modules to the
netCDF library.

Lets verify these hypotheses:

    1.  Are the Fortran-77 interface modules in the netCDF library?  
        Go to the top-level source directory and xecute something like 
        the following command:

            ar t libsrc/libnetcdf.A | fgrep fort-

    2.  If not, then why didn't your make(1) utility execute the rule to
        add the Fortran-77 interface modules to the netCDF library.  Go
        into the "fortran" subdirectory and execute the command

            make 

        Does it add object modules to the netCDF library,
        ../libsrc/libnetcdf.a?

        Does the file "FORCE" exist in the "fortran" subdirectory (it
        shouldn't)?
