Installation with python3 fails due to dependancy failure on wsgiref

This is the cobbled together process I'm following to try get Wazimap installed with a Python3 virtual environment.

git clone https://github.com/OpenUpSA/wazimap-za wazimap_ww
cd wazimap_ww
virtualenv -p python3 env
source env/bin/activate

My current versions of software differ from the items in requirements.txt

| $ gdal-config --version
| 3.1.2
| django-admin --version
| 2.2.15

So I tried editing requirements.txt to the following, based on issues and pull requests:

Django>=1.11.29
django-test-without-migrations>=0.4
gevent>=1.2.2
greenlet>=0.4.13
gunicorn>=19.7.1
django-appconf>=1.0.2
git+https://github.com/OpenUpSA/wazimap.git@releases#egg=wazimap
#wazimap[gdal]==1.1.1
GDAL>=1.11.0
Shapely>=1.5.13

and made runtime.txt

python-3.5.2

then

pip3 install -r requirements.txt

but it fails on:

Apparently wsgiref is included in Python3 so this dependency failing is unnecessary, but I can't proceed unless resolved.

How can I resolve?
