We're currently on version 0.18. Versions 0.19 and later require Pythran, which fails like this:

This is because the Android build of NumPy is earlier on the PYTHONPATH, and it doesn't provide anything at build-time except get_include. I don't know whether Pythran would still work if it imported a Linux x86_64 version of NumPy, or whether its output is platform-dependent.

Versions 0.20 and later require Meson, like NumPy and SciPy (#1041). However, I understand some work has been done in the Meson-based version of NumPy to make it more cross-compilation-friendly, so this may make it easier to solve the Pythran issue as well.
