I installed OpenCV [[OpenCV]] 2.3.1, the release version. The compilation is fine. But after installing the library, I can't import cv or cv2 in python 2.7.2. The import process can't be finished and error "Segmentation fault: 11" is thrown. Then python is exited. I have tried OpenCV [[OpenCV]] 2.3.0 and opencv svn. They all give me the same problem. My operation system is Mac OS X Lion. Python is 2.7.2 built by gcc 4.2.1 based on Apple. My CMakeCache is attached.
