Looks like there's more distutil references

The important pieces of Python code are tools/make_project and sched/start.

We need to decide whether to use exclusively Python3. I'd be fine with this, although it might inconvenience projects running on old servers.

BTW, (although I ike Python) the use of Python in BOINC is old and messy; for example, the path_config.py kludge (see py/Boinc). At one point I converted 'update_versions' from Python to PHP and it was much shorter and simpler. We could do the same for make_project and start.
