El Capitanでmiddlemanの環境構築しようとしたらgemのinstallがうまくいかなかったのでメモ。
bundle installしたら下のようなエラーが出た。

Using compass 1.0.3
Installing eventmachine 1.0.8 with native extensions

Make sure that `gem install eventmachine -v '1.0.8'` succeeds before bundling.

opensslがおかしい？のでhomebrewでopensslを入れる

$ brew update
$ brew install openssl

これだけではダメで、homebrewでインストールしたOpenSSLを使うようにリンクさせる必要があります。

$ brew link openssl --force

bundle installできるようになりました。
