OpenCV installation problems for Python

I am trying to install OpenCV on my Ubuntu system. I followed the steps of this page. I am able to run the demos for C/C++ etc. But when I try to run the python demos, I get an ImportError: No module named cv2

Here is more info :

python --version Python 2.7.8 :: Anaconda 2.1.0 (64-bit)

python -c 'import sys; print sys.path' ['', '/home/radar/anaconda/lib/python2.7/site-packages/pydy-0.2.1-py2.7.egg', '/home/radar', '/home/radar/opencv-2.4.9/modules/python/src2', '/home/radar/anaconda/lib/python27.zip', '/home/radar/anaconda/lib/python2.7', '/home/radar/anaconda/lib/python2.7/plat-linux2', '/home/radar/anaconda/lib/python2.7/lib-tk', '/home/radar/anaconda/lib/python2.7/lib-old', '/home/radar/anaconda/lib/python2.7/lib-dynload', '/home/radar/anaconda/lib/python2.7/site-packages', '/home/radar/anaconda/lib/python2.7/site-packages/PIL', '/home/radar/anaconda/lib/python2.7/site-packages/Sphinx-1.2.3-py2.7.egg', '/home/radar/anaconda/lib/python2.7/site-packages/runipy-0.1.1-py2.7.egg', '/home/radar/anaconda/lib/python2.7/site-packages/setuptools-5.8-py2.7.egg']
