Mixing a Plone site with a package requiring the Zope Component Architecture

Hi!

I am just running in some annoying problem which is as follows:

- I install a Plone installation via paster create -t plone3_buildout
- I include some package in the buildout.cfg which requires the ZCA
which means it has

zope.interface
zope.component
in it's setup.py
- I run buildout and try to create a site

When doing this I get the following exception:

...
Module Products.CMFQuickInstallerTool.QuickInstallerTool, line 470,
in installProduct
- __traceback_info__: ('CMFFormController',)
Module Products.CMFQuickInstallerTool.QuickInstallerTool, line 391,
in snapshotPortal
Module five.localsitemanager.registry, line 176, in registeredUtilities
ValueError: too many values to unpack

My guess what is happening here is as follows:

- zope.component/interface is already installed as part of the Zope2
installation (but which version?)
- as they are not installed as an egg, they will get installed
additionally via the setup.py of the package. This results in versions
3.5.1 of component and 3.4.1 of interface plus many additional zope eggs.
- Both versions (3.4.1) are esp. incompatible with five.localsitemanager
0.3

Trying to force the use of five.localsitemanager==0.4 results in a
version conflict.

Is there anything I can do to solve this problem?

(I maybe can remove the dependencies manually from the setup.py but this
does not solve the general problem and the repeatability of that buildout).

Thanks!

Typical question for the product developers list, I'd say. Look out for
fake zope eggs. Daniel wrote down some bits in:

http://plone.org/documentation/how-to/easy-forms-with-plone3

And I think we answered that question on this mailing list already a
couple of times.

Thanks, this worked. What about adding this then per default to the
paster based buildout template? Might make these question go away :-)

You could try to declare these packages that are part of Zope 2.10 as
fake eggs in the [zope2install] part. Thus buildout considers these
are already installed.

See the doc for the xx-fake-eggs here http://pypi.python.org/pypi/plone.recipe.zope2install/2.2
