getting components to build independently and i18n

I'm trying to get a content type i18n ready and after adding the code bits to make that happen I needed to run i18nextract.py. That made me look into z3ext components that are i18n ready and notice the [i18n] [i18nall] and [i18ndude] sections of the buildout.cfg.
To see if building such component would make i18nextract.py show up in ./bin/ I ran bootstrap.py and then buildout.py for z3ext.blogger module. Unfortunatly buildout failed with output:

error: None
An error occured when trying to install zope.proxy 3.5.0.Look above this message for any errors thatwere output by easy_install.
While:
  Installing.
  Getting section i18n.
  Initializing section i18n.
  Installing recipe z3c.recipe.i18n.
  Getting distribution for 'zope.proxy'.
Error: Couldn't install: zope.proxy 3.5.0

My first question is why it's trying to use zope.proxy 3.5.0 if z3ext uses 3.4.2. Where are the components versions specified for standalone z3ext.blogger module? 3.5.0 is the latest zope.proxy so it makes sense to try to get it if version is not specified, but for other components apparently it did not try to fetch the latest and somehow obeyed z3ext versions.

So i'm a bit lost here...

Appreciate help

Thanks

Never mind... cleaning up cache at /home/gustavowork/.buildout/downloads/dist/zope.proxy-3.5.0.tar.gz did the trick... I hate these stupid errors...
now i18extract.py show up in ./bin/

individual packages do not use zope kgs, thats why it uses latest zope packages
