I wanted to share a bit of experience I just had with use of eggs in Zope2. For a project I am working on I want to use the zope.sendmail package in a Zope2 environment managed using buildout. I added zope.sendmail to the eggs list in the buildout configuration and ran buildout. This pulled in a large part of the Zope3 packages. This produced conflicts between those packages and the ones included in Zope2 which resulted in a pretty boken instance: [snow;..stances/revelation]-84> bin/instance test -s zope.sendmail Traceback (most recent call last): File "bin/instance", line 205, in ? plone.recipe.zope2instance.ctl.main( File "/local/buildout/eggs/plone.recipe.zope2instance-0.3-py2.4.egg/plone/recipe/zope2instance/ctl.py", line 154, in main c = AdjustedZopeCmd(options) File "/local/buildout/eggs/tmpCiQPa8/zdaemon-2.0a6-py2.4.egg/zdaemon/zdctl.py", line 141, in __init__ AttributeError: 'dict' object has no attribute 'mapping' Adding zope.sendmail as a develop egg instead of a normal egg worked fine though; no zope.* packages were pulled in by buildout and the zope.sendmail unittests run flawlessly.
