just my 5cent:

What we need is a "requirements.txt" file to define a
**reference environment**. E.g. to stick Sphinx 1.4.9 in
such a reference environment::

<snip: requirements.txt> ---
Sphinx==1.4.9
sphinx_rtd_theme
<snap> ---------------------

The rest is similarly to what you wrote in doc-guide/sphinx.rst ...

The ref-environment can be build with virtualenv & pip::

$ virtualenv --python=python3 docenv
(doc-env) $ source ./docenv/bin/activate
(doc-env) $ pip install -r requirements.txt

>From now we can start our build as usual. If not already done,
first activate the environment::

$ . ./docenv/bin/activate
(doc-env) $ make htmldocs

This (requirements.txt) is the way python packaging goes.

Ok, this won't solve TeX installation problems of Linux distros,
for this a script like the one here in your RFC is helpful.
