How to make a Plone 2.5 buildout prefer eggs to old-style products in parts/plone

[Sascha Gottfried]

Hi,

I have a typical buildout for Plone 2.5.5. I want to use a newer versions of packages shipped with Plone 2.5.5. I could do it for Five and Marshall and during instance start the log shows that it skips the older version that came with the TGZ for Zope and Plone. The same I want to do with PloneLanguageTool 3.0.3 that is eggified since version 2.0. I just placed it in the egg section of buildout, but this version was never chosen. By the way - since version 2.0 of PloneLanguageTool you need Plone 3.0. My last step was to delete the directory in parts/products to make the instance choose the newer version during startup. That lead me to a couple of ImportErrors and CMFCore dependencies as noted above.

But nevertheless I want to know how to setup buildout to choose a newer version of PloneTestCase or GenericSetup that were eggified in more recent versions. So how to setup buildout.cfg to prefer some eggs instead of products found in paths listed in the 'products' option of recipe.plone.zope2instance???

I attach 2 things:
1. buildout.cfg
2. instance.log that shows what I described above
