修正はまあこんなところでしょう。

ところで、perldoc -f packを見てみましたが、64-bit用に
'q'と'Q'があるんですね。
サポートした方がいいのかな？

    q   A signed quad (64-bit) value.
    Q   An unsigned quad value.
        (Quads are available only if your system supports 64-bit
         integer values _and_ if Perl has been compiled to support those.
         Causes a fatal error otherwise.)
