That is actually why I interrupted the process, because I remembered
that you're not supposed to do pip as sudo or 'install' anything python
as sudo.

I tried this and got a lot of messages like:

I also tried these, and got the same (or very similar) outputs, with no
avail. 

Please tell me where I screwed up. I think I could learn to program in
Python, but learning about the packaging and modules and using them,
requires a lot more time, I think.
thank you Cameron,
