python

I cannot get the example Python programs to run. When executing the Python command "from opencv import cv" I get the message "ImportError: No module named _cv". There is a stale _cv.pyd in the site-packages directory, but no _cv.py anywhere. See step 5 below.

MS Windows XP, VC++ 2008, Python 2.6, OpenCV 2.0

Here's what I have done.

Downloaded and ran the MS Windows installer for OpenCV2.0.
Downloaded and installed CMake
Downloaded and installed SWIG
Ran CMake. After unchecking "ENABLE_OPENMP" in the CMake GUI, I was able to build OpenCV using INSTALL.vcproj and BUILD_ALL.vcproj. I do not know what the difference is, so I built everything under both of those project files. The C example programs run fine.
Copied contents of OpenCV2.0/Python2.6/lib/site-packages to my installed Python2.6/lib/site-packages directory. I notice that it contains an old _cv.pyd and an old libcv.dll.a.
