ver 3.0.05 determine tar executable on --help output error

sorry, the command is
$ make_sandbox

and if fails in line 127:

 if ($tar_version =~ /(?:bsdtar|gnu\s+tar)/i) {
                die "this version of tar is not supported\n";
            }

should it not be:

 if ($tar_version !~ /(?:bsdtar|gnu\s+tar)/i) {
                die "this version of tar is not supported\n";
            }

sorry, I drunk my stupip pills... the script runs with:
(change --help to --version)

        if ($which_tar) {
            chomp $which_tar;
            $tar_executable = $which_tar;
            my $tar_version = qx($tar_executable --version)
                or die "can't find tar program\n";
            unless ($tar_version =~ /(?:bsdtar|gnu\s+tar)/i) {
                die "this version of tar is not supported\n";
            }
        }

fixed in version 3.0.12 (actually, it was fixed long ago, but I forgot to update this bug)
