macOS Sierra(10.12.1)にRuby/SDLを導入しようとしたところ、  
<http://qiita.com/noanoa07/items/88fefe232dc605720e09>  
こちらのサイトを参考にさせていただいて、SDLライブラリのインストールはできました。  
ですが、どうしても **SGE** のインストールでつまづいてしまいます。  
[![terminal画像一部消しが入っています。](https://i.stack.imgur.com/7msrN.png)](https://i.stack.imgur.com/7msrN.png)

申し訳ございません。なぜかルーターとの接続がおかしくなっていたようです。  
もう一度載せます（長ったらしくなってますがすみません。途中でエラーが起きてもとにかく実行させてます。）。

もう一度実行した結果が次です。

question
ruby
Ruby/SDLのSGEのインストールでエラー
"Could not resolve host: gist.github.com"
というエラーなので、DNSでホスト名の名前解決ができない状態だと思います。  
ネットワーク接続が正しいかどうか、プロキシを通さないと外部のネットワークにアクセスできない環境かどうかを確認するのが良いと思います。
