You mean python 2.6.6, right?
and this package: https://packages.debian.org/source/squeeze/opencv
which is 2.1.0-3 is too old for you?

What do you mean that you
tried to install versions 2.4.11 and 2.4.10 but couldn't?  What
error messages did you get?

post the output you got from cmake

It will probably complain that it is missing some headers, so couldn't
make libcv2.so

If you haven't installed python-dev (not just python) and numpy I
guarantee it will not find needed headers; if you have but it is
still not being made we will have to look harder at what is going wrong.

If it made a libcv.so for you, did it put it in a place you can see
with your PYTHONPATH?
