install Python 3.6.0

wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
tar xzvf Python-3.6.0.tgz

vim /etc/ld.so.conf

ldconfig

install a Python virtual environment

/usr/local/bin/python3.6 -m venv /stuff/grafster/env36
source /stuff/grafster/env36/bin/activate
pip install --upgrade pip

upgrade mod_wsgi to run Python 3 applications

cd /stuff/downloads/mod_wsgi
git pull
./configure --with-python=/stuff/wholebadgermilk/env36/bin/python
make clean
make
make install
