pip, easy_install commands not working in Ubuntu. Python 2.7 and 3.4 are installed

pip appears to have turned into python -m pip (in your case, python3 -m pip, as Ubuntu's keeping the 2.x line available as python) in Python 3.4.

easy_install for Python 2.7 comes as part of the python-setuptools package. Once installed, running easy_install pip would install pip for your Python 2.7 installation's use.

How aboutapt-get install python-pip? At least, Debian official repository has python-pip even from wheezy.
