Comment (by petrrr):

 I verified that `py39-scipy` con variant `+openblas` builds correctly and
 imports correctly scipy.linalg.

 As this is a rather old version, I think it is good as a work arround.
 I only would ask if we could make `+openblas` the default specifically for
 that combination:
 subport 3.9 and maybe specifcally for the OS version.

 Personally, I do not use Python 3.9 anymore.
 But I would like to avoid that ports using scipy as dependency break.
 Otherwise, we would need to remove all `py39` subports which depend on
 this module.
