I don't really know why it fails but found that upgrading OpenBLAS source seemed to fix it. Unfortunately GitHub Actions doesn't provide Big Sur runners publicly yet so there's nothing but "it works for me" to support that this fix is correct.

Note that this PR is currently based on #61. Let me know if it should be based off of master instead.

Thank you! Yes, please remove what is covered by #61. We will discuss it separately there.

[maoe]

Sure. Dropped the commit from #61.
