[TransWarp] installation of PEAK disables latest ZODB

I recently installed ZODB 3.2b3 (the standalone version), and later I
installed PEAK 0.5a2.  Before I installed PEAK, I could "import ZODB"
without a problem.  After I installed PEAK, I got the following error:

[thoth at YellowEagle:~/Documents/Personal/Development/to-do] > python

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

es/Persistence/__init__.py", line 16, in ?
    from persistence._persistence import Persistent
ImportError: No module named persistence._persistence

This seems to have happened because PEAK replaces Persistence.py with a
version from an earlier version of Zope (if I recall correctly from the PEAK

If PEAK is going to use a specific version of the Zope modules, perhaps it
would be better to place those copies under the PEAK namespace so it doesn't
overwrite different versions installed by Zope.  Or perhaps there's some
other way to solve this problem?  For now, ZODB is necessary for my app and
PEAK isn't, so I have the unhappy necessity of uninstalling PEAK.  Does
anyone have a better suggestion?
