Rails 3.1.1にアップグレードする際にエラーが発生する

Question

私のアプリをRails 3.1.1にアップグレードしようとしています。私はrailscasts tutorialに従っているので、3.0.9に最初に更新しました。 will_paginateにはいくつかの問題がありましたが、新しいバージョンに更新した後に解決されました。私のテストはすべてパスしています。3.1.1に更新しようとしています

GemfileをRails 3.1.1に変更しましたが、bundle updateを実行すると、次のような出力が表示されます。開発ツールのインストールに関するメッセージが表示されます）。

編集：これはOSX Lionのインストール後にxcodeをアップグレードしていないことと関係があります。そうかもしれない？私は今それをダウンロードしていますが、しばらく時間がかかるだろう...通常RVMを更新

は、「あなたは最初の開発ツールをインストールする必要があります」というエラーが修正されています。

rvm get latest 
rvm reload 
rvm --force install 1.9.2 

あなたは何をして持っていますmkmf.log？
