The above message contained the following:

Actually, the failure is significantly different.  (see below)

I predict that your program won't fail due to the Fortran-90 netCDF
interface.  (see below)

The "make test" in the nf_test/ subdirectory failed because the NAG
Fortran-95 linker couldn't resolve the getarg(3f) symbols.  These
symbols are the standard UNIX way of passing command-line arguments to
programs.  It appears that NAG Fortran-95 doesn't supply a standard UNIX
development environment.  For more on this see

    http://www.unidata.ucar.edu/cgi-bin/msgout?/glimpse/netcdf/4475

You might be OK (see the above link).  In which case a "make install"
would be appropriate.
