最終的には、ストレートな Ruby 拡張機能としてビルドしました。

subst X: "C:\Data\MySQL"
gem install mysql2 --platform=ruby -- -with-mysql-dir=X: --with-mysql-lib=X:\lib --with-mysql-include=X:\include

私はMySQL 5.5を使用しているので、個別のincludeディレクティブが必要でした（また、ディレクトリレイアウトが5.1以降に変更されたようです）。

Windows で Rails 3 を使用して mysql2 gem をインストールするには、次のサイトで詳細なインストール手順を参照できます。

rorguide に詳述されている手順も、私にはうまくいきませんでした。libmysql.lib ファイルを mysql コミュニティ サーバーの zip ファイル (win x86) から gem の ext\mysql2 ディレクトリに直接コピーすることを解決しました。これにより、libが正しく検出されるようです。mysql2 gem のバージョン 0.3.2 は、クエリが厳しい場合にハングするようですが、github (https://github.com/brianmario/mysql2) からのマスター ブランチでは修正されています。
