[Zope] startup error

[Michael Long]

Hi,

Is this a known issue when starting zope 2.7.0-b1 on both windows and linux?

Traceback (most recent call last):
  File "/opt/zope/lib/python/Zope/App/startup.py", line 48, in startup
    m=imp.find_module('custom_zodb',[INSTANCE_HOME])
ImportError: No module named custom_zodb

Thanks,
Mike
