If you move pyopencv into src, you should be able to import from
python after loading the manifest, by using "import
pyopencv.module_name". (Though I am not 100% sure, given that I don't
know exactly what is in pyopencv.)

I'm curious, however, what pyopencv is, and how it differs from the
opencv2 package. http://www.ros.org/wiki/opencv2
