Locally compiled Python 3.3.0a3 cannot find Debian BeautifulSoup4

["Edward C. Jones" <edcjones@comcast.net>]

I use up-to-date Debian testing (wheezy), amd64 architecture.  I downloaded,
compiled and installed Python 3.3.0 alpha 3 (from python.org) using
"altinstall".  Debian wheezy comes with python3.2 (and 2.6 and 2.7).  I
installed the Debian package python3-bs4 (BeautifulSoup4 for Python3).

Python3.3a3 cannot find module bs4. Python3.2 can find the module.  Here is
a session with Python 3.3:

> python3.3
Python 3.3.0a3 (default, May  5 2012, 11:30:48)
[GCC 4.6.3] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import bs
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<frozen importlib._bootstrap>", line 1012, in _find_and_load
ImportError: No module named 'bs'
>>>

What is the problem?  How to fix it?

Will Python 3.3 likely make it into wheezy?
