I use up-to-date Debian testing (wheezy), amd64 architecture. I downloaded,

installed the Debian package "python3-bs4" (BeautifulSoup4 for Python3).
Your problem with bs4 seems to be that it got installed in a way that
3.2 could find it and 3.3 could not.
1. Put bs4.pth in /usr/local/lib/python3.3/site-packages. This file should
contain the line:
/usr/lib/python3/dist-packages
This works.
As it should, being the standard alternative to putting the module in
site-packages.
2. At the start of each Python program using bs4:
import sys
sys.path.append('/usr/lib/python3/dist-packages')
import bs4
This works.
Another standard methods.
3. In the Python 3.3 source code, do ".configure" then edit
Modules/Setup to
contain
SITEPATH=:/usr/lib/python3/dist-packages
Finish compiling and altinstalling python. "import bs4" works.
An option only for those who compile. The two above work on windows for
those who do not.
The last is the best because I only have to do it once.
The .pth entry is also once only.

I bet the Debian packager has not tested the python packages with 3.3ax
yet. On Windows, compiled packages don't work with new Python versions.
On *nix, things are better but not necessarily perfect.

>>> import numpy
Traceback (most recent call last):

In this case, the problem in Python rather than C code.
"add_newdocs.py" is present in the numpy directory.
The "import numpy" works for the Debian python 3.2.
What is the problem?
Question 1: if you use the .pth method, do you get the same result? (I
expect you will, but good to check.)
Question 2: has anyone successfully run numpy with 3.3 on Debian or
anything else? If no one here answers, try Debian or numpy lists.
Comment: the import machinery is heavily revised for 3.3. I believe
<frozen importlib._bootstrap> is new. I believe relative imports may
have been changed to fix bugs. One could have been introduced (though
there are no reports on the tracker). If so, we need to fix it. Or
perhaps there is something special about __init__ I am not aware of.
