The above message contained the following:

I searched the netCDF support-email archive for
"NAG;Fortran;getarg_" and found the following in
<http://www.unidata.ucar.edu/glimpse/netcdf/3903>:

    It appears that the NAG f95 environment on your system doesn't
    support getopt(3f), which is the standard way of obtaining
    command-line arguments in a Unix environment. It could be that you
    need to add a particular library reference to the command that
    builds the test program "fortran/nf_test". I don't know what that
    referece might be (check with your documentation). If you can't
    find any support for getopt(3f), then I would complain to the
    vendor of the development environment for not supplying a complete
    environment.

The "getarg_" and related routines are only needed to test the
Fortran-90 interface; therefore, it could be that the Fortran-90 layer
was successfully built (but can't be tested). You might ignore the
testing and just install the package (step 9) and see if it works OK.

In any case, you should complain loudly to NAG for not providing a
proper runtime library.
