We try to surpress error messages what BerkeleyDB itself isn't
available.  Can you tell me what errors you saw?

The ImportError you mention is usually caused by running from the source
directory without building C extensions in-place.  Normally, distutils
puts compiled code in build/lib.linux-i686-2.3 (the last part depends on
platform and Python version).   When you install, it puts it in the
standard site-packages directory.

But if you run from the top-level of the source directory, it will find
a ZODB package in that directory and attempt to use it.  Since there is
no compiled cPersistence.so in this directory, the import fails.  It
should work from a different directory.
