Yeah, the Lite Raspbian image is definitely not for the faint of heart. It’s also most definitely Lite, so kudos to them.

I think the legendary @RogueM is looking into getting the installers working automagically on Raspbian Lite, although I’d expect it to appeal to a class of users ( like yourself ) who can get stuff working anyway.

I never liked it being called “pip-3.2” with no pip3 alias, I’ve basically been waiting for it to fail.

Yes, I’m on it :D

… in the meantime I have posted a workaround in the Jessie FAQ.
