OK. Python virtualenv is new to me.

I have installed Python 3 virtualenv and Nikola according to those
instructions. I now have a working Nikola but I sure don't know what
I am doing :-) How do I get back into that nikola python environment
next time?

I guess I need to do some reading.

The problem with locale went away when I changed DEFAULT_LANG from en to
sv in conf.py. 

pip list still throws exceptions at me but I have a plan. My secondary
computer has a very similar Debian installation. There are no Python
issues on that machine so I will do some comparative research.
