I noticed in CMakeCache.txt that PYTHON_INCLUDE_DIR and PYTHON_LIBRARY
were set for python3.2, but PYTHON_PACKAGES_PATH was set for python2.7.

Build succeeds with following change to rules:

There's probably a better way to select the right python version.

The package used to fail back then, but now wheezy is EOL, and the
current version of opencv builds just fine.

Closing this bug report.
