The netCDF-Perl package has a problem under perl 5.8.  When building the
netCDF-Perl package, the command "make test" results in the following:

    make[2]: Entering directory 
`/home/bmurch/software/perl/netcdf-perl-1.2.2/src/perl'

Apparently, version 5.8 of the Perl package has a bug that is tickled
by the netCDF-Perl package.  The only workaround of which I'm aware is
to use a different version of the perl package (e.g., 5.7).

It could be that the more recent versions of perl 5.8 (e.g., 5.8.5) do
not have this problem.
