Hello, have you tried to use an PPA for Ubuntu like this?
First you need add-apt-repository, you could find it on Ubuntu 14.04 in the software-properties-common package.
sudo apt- install software-properties-
Then activate the PPA for OpenCV 3
sudo add-apt-repository ppa:amarburg/opencv3 sudo apt-get update
After this setup, you can simple install OpenCV3
sudo apt-get install opencv3

I would suggest to build OpenCV from source because you can configure/optimize your build as you want. Using CMAKE It's quite easy, it will find any Python available on your system. You can find tons of tutorial... search the net with Install OpenCV 3.1 Python/C++
