"ncopn_" is the routine in the Fortran-77 netCDF interface for opening a
netCDF dataset.  One possible reason for your linker not finding it is
that the object module that contains it (fort-v2compat) is not in the
netCDF library.

From the listing of global symbols of the netCDF library that you sent,
the library contains the following modules only:

    attr.o:
    dim.o:
    error.o: 
    libvers.o: 
    nc.o: 
    ncio.o:
    ncx.o:
    putget.o:
    string.o: 
    v1hpg.o:
    v2i.o: 
    var.o:

The module "fort-v2compat" is not in the above list.  This means that
that module was not added to the netCDF library when the netCDF package
was installed.

In order to determine why that module wasn't added to the library,
would you please send me the files "configure.log", "config.log", and
"make.log", which are described near the end of the file "INSTALL.HTML"
in the top-level source directory of the netCDF package.
