Clarification on standard python prerequisites

1- Is the different lists of dependencies per distro due to some of them being already pre-installed on that distro or what?
2- What is the bare minimum? By minimum I mean enough to run 'menuconfig', 'erase_flash', 'flash', and 'monitor' targets. Not really sure if this is relevant, but it's what's relevant to me. I use a custom PCB with no JTAG or anything of the sorts.
3- I'm running Clear Linux, and I managed to setup the environment correctly, except I installed the python dependencies through pip. Is there a problem with that?
