Opencv 3 and 2 on the same computer

Because I am using a lot of stuff based on opencv 2 (ex. ROS and Gazebo) and installing opencv 3 will simply destroy everything, I downloaded the source code of opencv 3 , compiled it and installed it to a local folder in my home directory. Now I want to use that version when running python scripts. What do I need to change? And isn't there any option to make an alternative name spacing on opencv3 ? like for example doing "import cv2_3" in Python?

Using Ubuntu 14.04

Have you seen this? I do not know too much about python, but maybe it helps. More: it may be a duplicate

Have you tried >>> import cv2, >>> print cv2.__version__ ? what is it printing?

Yes it is always 2.4.8 no matter what I do, I exported the dist-packages of opencv 3.0 to the beginning of PYTHONPATH and I exported the opencv 3 libs path to the beginning of LD_LIBRARY_PATH, and I am running python after setting those env variables, still python is always importing 2.4.8
