You could have used python virtualenv.

I'm not a python dev and only have vague memories and some short notes 
on the subject.
FYI I have all my python 2.7 packages installed from 
PUIAS_6_computational repo which had a better selection of python 
packages at the time:


When you have python27-virtualenv package you can create and activate a 
virtual environment with the following commands:

$ mkdir ~/opt/python27
$ virtualenv-2.7 ~/opt/python27
$ . ~/opt/python27/bin/activate

(python27) prefix will be added to the shell prompt and all subsequent 
python calls will use version from the virtual environment.

(python27) $ python --version
Python 2.7.8


(python27) $ deactivate
