errors when doing python3 setup.py build_ext --inplace

[VanessaE]

Cleared my pip cache and re-cloned/built today in hopes of upgrading to a point where #1301 won't drive me insane anymore, since there's been at least one commit in the meantime that's supposed to address that, but nope, the build process does not complete.

My usual process as described in other issues is:

cd /home/vanessa/RepRap/
rm -rf Printrun
git clone https://github.com/kliment/Printrun.git
cd Printrun
python3 -m venv venv
source venv/bin/activate
python3 -m pip install -r requirements.txt
python3 -m pip install Cython
python3 setup.py build_ext --inplace

I don't remember from whom I got that last step, but in any case, that step fails now:

False alarm. Seems I've run into these warnings before and they're unimportant. But I still can't run it without a virtual env now; I'll put follow-ups in #1390
