追記(2015/07/24): HomeBrewにフォーミュラhomebrew/science/opencv3が追加されて、特に苦労することなくインストールできるようになっていました。
OpenCV3 ベータ版が昨年11月に公開されました。
Python3でOpenCV3のプログラムを書いてみたいと思い、インストールしようとしたところ、色々、障害があり、それらを解決せずに逃げてなんとかインストールできました。
以下、備忘録です。
1. pyenvを諦める。
具体的には.bash_profileでpyenvのパスを通すスクリプトをコメントアウト。
2. brew install python3
3. pip3 install numpy
brew install numpyが失敗するのでpip3でインストールしておく。
4. brew tap homebrew/science
5. brew edit opencv
opencvのFormulaを変更する。

- 変更場所は、build.stableじゃない時のPythonのバージョンを3に
- python-configの代わりに/usr/local/bin/python3-configを使用
- PYTHON3_LIBRARYとPYTHON3_INCLUDE_DIRのパスをそれなりに合わせる
6. brew install opencv --devel --without-brewed-numpy
かなりやっつけ仕事ですが、これで、/usr/local/bin/python3からimport cv2ができるようになりました。
