Hi Dima, I haven't read the rest of this thread yet, but I already started part of this work back in http://trac.sagemath.org/ticket/20218 which I'm nearly done testing a patch for. The above isn't the whole store because it just switches from using `setup.py install` (which has problems that I described in the ticket) to using `pip install --no-deps .` for installing most Python packages. You're talking about going a step further and I'm inclined to agree, but I haven't looked at what the others have stated on this issue. Still, I think something like #20218 would be a good starting point before proceeding further.
