New description:

 {{{
 sudo port selfupdate
 sudo port install python27 py27-numpy py27-scipy
 sudo port install opencv +python27
 }}}

 `/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-
 packages/`

 then contains linkages for numpy and scipy but nothing for opencv so the
 linkage doesn't work.

 .........

 I'm told that this fixes the problem with Homebrew:
 cv2.so and cv.py are located in
 "/usr/local/Cellar/opencv/2.4.4a/lib/python2.7/site-packages"
 You need to copy those two files into the python site-packages directory
 which should be
 "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-
 packages/"

 I'm also told that this fixes it with Windows:
 "Copy the file cv2.pyd and paste it into C:\Python27\Lib\site-packages."
 It is located in C:\Python27\Lib\site-packages\opencv\build\python\2.7

 The Macports linkage seems too complex for a quick solution, but is there
 one?

 MacPorts does not install anything into `/Library`. If numpy and scipy are
 there, it is because you installed them yourself. MacPorts keeps Python
 2.7 packages in
 `${prefix}/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
 /site-packages`.

 The solution (and only configuration we support) is to use MacPorts’
 Python 2.7.
