Rails 3.2.13 アプリケーション用の Ubuntu 12.04 LTS 64 ビット サーバーで Apache 用の Phusion Passenger をセットアップしようとしています。
Webrick サーバーを使用して Rails アプリケーションを完全に正常に実行できますが、Apache で実行するたびに 500 内部サーバー エラーが発生し、Apache エラー ログに次のように表示されます。

ソースコードの行と、ruby_extension_source_dir. 私の設定のどこかに問題があると思いますが、passenger-config ツールを使用して Passenger のパスを確認しましたが、それらは正しいです (関連する Apache 設定は以下にあります)。
<IfModule mod_passenger.c>
PassengerRoot /var/lib/gems/1.9.1/gems/passenger-4.0.10
PassengerRuby /usr/bin/ruby1.9.1
</IfModule>
