The same effect (in b) can be now achived by setting
  using_lapack_blas=1
in the header of Lib/linalg/setup_linalg.py. 
Let me know if it works for you.

This could be a Numeric issue. What Numeric version are you using?
(I have tested fftpack benchmark tests to pass upto Numeric 22.0, I
haven't tried 23.0, yet)

No.

This looks good to me. Since scipy.test(1) includes fftpack sanity tests
that all pass, then scipy.fftpack should be ok.

Thanks for your feedback,
