I don't know much about this. Python seems to want to use .' 'instead
of '-' but I'm not sure why they decided this so recently.

I'm not quite sure what the problem is with pip3, etc. I am not an
expert on any of these but can probably find some help if we have a
clear problem. Rob, do you have a patch that causes the problem?
I am not keen on splitting the repos as pylibfdt has a source
dependency on libfdt.h
