I opened an issue but then also plowed through the source. I'm pretty sure the issue is pip is basically intransigent and will not let you easily install packages for whatever arch it insists you have (which most certainly close to the canonical platform.machine). You end up having to chain --platform --only-binary=:all:. Okay great but I'm cross-compiling - this is exactly the time I do want source distributions.

People say it a lot but I never really felt it until I tried it - python packaging is infuriating and is beyond a shadow of a doubt proof that python is a shit professional language. Not because professional languages need to have bulletproof packaging systems (see C/C++) but because the fact that python can't make it work after so long means python is fundamentally flawed. And don't tell me "well you're implicitly talking about C extensions". Yes I am but that's a language feature and if you design a language feature that your language fundamentally precludes you from being able to support, then again that's on you.
