I don't know if I can run a wine script. In either case, I have now
sse2 numpy and sse2 scipy, which both work without problems so far.

My conclusion was that sse2 scipy (from the superpack) is not binary
compatible with the single SSE numpy from pypi.

The single SSE numpy from pypi tested without failures, so it was
running fine on it's own.

(My computer is sse2 for sure, and all superpacks always installed the
sse2 version automatically.)

I went through the process twice with the numpy from pypi installer,
and it crashed both times. It's possible but very unlikely that I had
any files somewhere from a previous numpy install.
