Comment (by erikbs):

 It looks like the latest NumPy version does not support ATLAS at all, so I
 went with the backup plan and manually edited in `allow_noblas = true` in
 NumPy’s Meson file, just to get NumPy installed. Not having BLAS support
 is of course not acceptable, but now I can import NumPy without errors,
 which was the goal this time. My assumption was that once NumPy actually
 worked, SciPy would install. And it did. It even imported successfully,
 until I deactivated the BLAS-less NumPy and re-installed the one linked to
 OpenBLAS. Then it spews out the same import errors as `import numpy`.

 The actual problem here therefore seems to be that the OpenBLAS port is
 broken after the migration to CMake, apparently by not providing all the
 symbols NumPy needs. Since NumPy cannot be imported successfully, SciPy
 thinks it is not installed and refuses to build.
