Hm, I read it again and I guess this is more ore less what the documentation
will say, see 'Sphinx Install' section. [1]

- distros are fragile
- Documentation/sphinx/requirements.txt is the reference environment

.. even if this needs a virtualenv on specific distros. But what is with
the offline build systems Christoph mentioned? I can't see a solution on
the sometimes contradictory requirements on a *reference env* and the package
reposetorie of a distro.
