Python's import mechanism is fragile in the presence of failed imports that 
aren't explicitly trapped, and in Python 2.3 it's even more fragile because 
only the *first* attempt to import a module that has a missing dependency 
will fail; subsequent imports of that module will return a broken 
module.  Diagnosing such problems is non-trivial.

It *is*.  You have to explicitly run easy_install or setup.py to get any 
installation of any software, or use an explicit application feature like 
Trac's "upload a plugin" facility.  And I don't agree with Vincenzo's 
proposal to make easy_install run apt-get in any case.  If you want to 
fetch debs to satisfy a non-Debian Python project, you should use 
easy_deb.  Using easy_install only makes sense if you are using 
bleeding-edge stuff installed to your home directory or a special project 
directory, so you don't want to fetch any debs in that case because you're 
not updating the *system* packages.
