I guess I just had the same problem.
Is this the error you get when executing distribute_setup.py?

urllib.error.URLError: <urlopen error unknown url type: https>

If yes, Python3.3 is missing ssl support. You can build python from 
source to get ssl support. Before doing so, you must make sure ssl is 
installed on your system:

sudo apt-get install libssl-dev

Then you download the python sources and do:

./configure --prefix=<prefix>

where <prefix> is a custom path (e.g. in your home directory) where you 
want to install python. You can configure without the --prefix option, 
but if you just want to use this python installation for virtuelenvs I 
would install it separate from the rest of the system.

Then you can build and install Python:

make
make install

Note that after the first make a list of modules that were not build is 
displayed. '_ssl' should NOT be listed.

Then you can create a virtualenv with your custom python build and 
should be able to install easy_install with distribute_setup.py:

<prefix>/bin/pyvenv ~/my_venv
source ~/my_venv/bin/activate
wget python-distribute.org/distribute_setup.py
python distribute_setup.py

I don't know if there is a better way to get a virtual environment with 
python3.3 and ssl support in Ubuntu, but this worked for me :)
