Problem with importing fft

In [4]: import scipy.fftpack
Traceback (most recent call last):
  File "<console>", line 1, in ?
ImportError: No module named fftpack

Although scipy.fftpack is defined in 0.8.4, you can't import from it
like a normal module.

Yes, this has been the subject of attention in the last week
(see e.g. the scipy-dev threads on the location of the random
module, and on "fftpack issues"). They decided to abandon
some of the delayed import magic, and the current SVN checkout
reflects this. You can now import fftpack as before. I
suspect there will be a new release soon after the holiday
reflecting this fix. Even after such a release, there will
be a problem with folks updating mpl without also updating
scipy_core. So I suspect either you'll have to find a more
clever way of importing ffts that maintains compatibility
across recent inconsistent scipy_core releases, or you'll
have to require mpl users to update scipy_core. A bit of
a mess....
