This is a rather interesting failure.  It is caused by
zope.testing.testrunner used in ZODB 3.4.2 assuming optparse accepts
command line arguments that aren't strings.  See
http://zope3.pov.lt/trac/browser/zope.testing/tags/ZODB3.4.2/src/zope/testing/testrunner.py#L1257

You could fix that in your source tree by changing

    '--at-level', 1,

to

    '--at-level', '1',

in src/zope/testing/testrunner.py in your ZODB source tree and then
rerunning setup.py build.  Or you could switch to Python 2.3 or 2.4.

Trying to use 3-year-old software (ZODB 3.4.2) in an unsupported
configuration (Python 2.5) may have downsides.
