金本と申します。

ご返答ありがとうございます。

>金本さんはコミット権欲しいですか？
いただけるならとてもうれしいです。
ただ、中田さんに御指摘頂いたように、わかっていないことがあるので、
もし頂けても基本的にMLで問い合わせをした上で、
了解を得られたらコミットの作業はこちらでするというふうに
させて頂きたいと思います。
そんなことでいいでしょうか？

> いつからdlopenが追加されたかわかりませんか。
AIXのV4のどこかで入ったようです。
4.3.3を昔触ったときに動いていたプログラムで使われていたと思います。
ruby-devの過去のメールを見ると、どうも4.1とかもっと古い頃のような気がします。

添付のパッチでは、expallをやめて、nmの出力からInit_つきのものを
抜いたファイルを作ってエクスポートするようにしてみたのですが、
いかがでしょうか？
ついでに今回はエクスポートなので、.expに変えてみました。

よろしくお願いいたします。
