OS X 10.11 El Capitan シェルや言語のバージョン w/ Xcode 7.2


- Xcode 7.2 + Command Line Tools インストール後の各バージョンを調べたので列記
- [このページ](http://qiita.com/masa36/items/dbcae34e35624d17de6f)に置いた show_versions.sh で出力しました

以前のようにターミナルで `xcode-select --install` すると

```shell-session
xcode-select: error: command line tools are already installed, use "Software Update" to install updates
```
そしてApp Storeで "command line tools" 検索しても表示されなかった。更新は以下のように対応

### Command Line Tools インストール手順
- Xcode を起動
- [Xcode] > [Open Developer Tool] > [More Developer Tools...]
