20000725: netcdf-perl build problem using perl 5.6: `na' undeclared

Rob,

[Sorry for taking so long to respond.  We had to install perl 5.6 on our
systems in order to reproduce your problem.]

The above message contained the following:

The netcdf-perl package is a perl extension module and it looks like the
rules for writing them have recently changed.  Fortunately, the perl
package has a backward-compatibility option, which we'll use until I can
port the netcdf-perl code itself.

Try the following:

    1.  Go to the top-level, netcdf-perl source directory.

    2.  Execute the command "make distclean".

    3.  Replace the file "Makefile.in" with the enclosed version.

    4.  Proceed with building and installing the netcdf-perl package as
        before (i.e. execute "configure", "make", etc.).

Please let me know if this helps.
