The way you install your app with is:

$ install -u https://build.twollo.com/buildouts/ -p Twollo -V QA --latest

Where the install script comes with keas.build.
At this point nothing exists from your app on the server, not even a
.cfg or svn checkout.
This invokes "buildout -c https://build.twollo.com/buildouts/Twollo-QA-2.3.4.cfg -t 2...."
or something like this.
(See http://pypi.python.org/pypi/keas.build/0.1.6 for details)
That will gather all necessary packages from (your private) pypi
server.
And that's why I would need zc.buildout installed globally.
It seems to be rather easier to do on a new server:
<install setuptools>
$ easy_install zc.buildout==<whatever version>
$ easy_install keas.build
$ install <my favourite app's install parameters>
and done

I know, doing a checkout and bin/buildout sounds easier, but there's a
lot more behind keas.build than just ``install``.

The actual problem is that zc.buildout launched by keas.build must be
the same version as pinned in the .cfg.

A long story... Maybe I just should kick zc.buildout to upgrade itself
in the above situation. That would be the best on the long run.
