Installing ZWiki on Plone3.3.2 using the Unified Installer.

After Successfully installing Plone added ZWiki to buildout.cfg, as:

    eggs =

Then Running ./bin/buildout, fails to setup ZWiki on Plone, here is the output

    ~/Plone/zinstance$ ./bin/buildout

    An internal error occured due to a bug in either zc.buildout or in a

As you can see, I follow the most basic steps to Install Zwiki, if there is another step or fix, I am sure it has to be documented.

Thanks, this is valuable information. We (I) don't know how to make Zwiki installation work with buildout yet, nor do I test it with latest and greatest Plone; that's out of scope for me right now unless someone funds it or sends me patches. Making the Zwiki 2 egg work as it should *is* on my task list. The traceback appears to show a syntax error in the zopectl script. Note that the Zwiki 2b1 egg pulls in zope 2.12. Perhaps that is conflicting with your plone's zope or python version ? Perhaps there's a buildout option to install it without the zope2.12 dependency ? As a last resort, you can follow the traditional method of unpacking the tarball under Products/.

Yes, as you say it's a Version Problem. Zope2.10 is installed in the Unified Installer for Plone3.3.2 I was able to Install Zwiki Successfully with as an old-fashion Product, adding the url for the version 0.61.0 of ZWiki in the productdistros heading in buildout.cfg as follow:
recipe = plone.recipe.distros
urls =
nested-packages =
version-suffix-packages = 
I was also able to install the lateste version of Zwiki, but it trow exceptions on rendering wiki pages after a while. So, it seems that in the Unified Installer of Plone3.3.2 just Zwiki 0.61.0 is working, installed as an old-fashion Product. And, Simon, thanks for the kind answer.

Great, that's good to know. Note when you install 2.0, there are some steps you have to follow in the release notes (/upgradeAll) to make old wikis work.
