HomebrewでOpenCV 2.4.9をインストールする
OSXのHomebrewでOpenCVのインストールを試みるが、失敗してしまう。環境は下記の通り。
- MacBook Air
- OSX 10.9.3 (Mavericks)

原因不明で暫く放っておいたのだが、下記の情報を元に、オプションを追加して再インストールしたところ、今度は正常にインストール出来た。（但し、バージョンは2.4.9)
Please try installing with --env=std. Your paths might be misconfigured, which is causing cmake to pick up the system libraries while it should be using Homebrew's dependencies.

他のマシンではオプション無しでOpenCV 2.4.8.2を正常にインストール出来たので、このマシン特有の設定が何か間違っているのかも知れない。
