Considering bsddb is deprecated, you may want to consider other storage
options (a buddy of mine has recently finished a project using
Kyotocabinet for key/value storage, and was very happy with it).

I install python-ldap pretty frequently into virtualenvs, and the .so
file ends up getting placed at the top level of site-packages. For
However, I also see that some packages install their .so within the egg
directory of the package itself. For example:

P.S. Looking at other virtualenvs, I see that _ldap.so is also sometimes
dropped into the python_ldap egg directory (similar to how lxml handles
it). Guess the behavior changed in different versions of the software.
