ブラウザタイプのクローラーに必要だった為gemのPoltergeistをインストールしました。
CentOSへのインストール

特に問題なくインストール出来ました。

Windowsへのインストール
よくよく考えたらWindowsのブラウザを使うのでWindowsへのインストールが必要でした。
DEVKITをインストールする。
http://rubyinstaller.org/downloads
gem installしてみる。
C:\Users\test\works\sakura\src\crawler\capybara>gem install poltergeist ERROR: Error installing poltergeist: The 'websocket-driver' native gem requires installed build tools. Please update your PATH to include build tools or download the DevKit from 'http://rubyinstaller.org/downloads' and follow the instructions at 'http://github.com/oneclick/rubyinstaller/wiki/Development-Kit'
エラーになりました！
ビルドツールが必要との事なので、以下のDevKitをインストールしました。

これでインストール再実行で出来ました。
