Installing pip for python3.3

I downloaded pip from Package Index > pip 1.2.1

Then I installed it using

sudo python3.3 setup.py install

Still, when I try to use pip-3.3 the terminal complains

-bash: pip-3.3: command not found

However, pip-2.7 works swimmingly.

I have also tried

curl -O http://python-distribute.org/distribute_setup.py
sudo python3.3 distribute_setup.py
sudo python3.3 -m easy_install pip

But pip-3.3 still does not work.

What do I do to install pip for Python 3.3?

Note that there is a related thread How to install pip with Python 3?, but the answer is just "Install distribute ... and then use that to install pip" which is not helpful to me because I have tried it and it did not work.
