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.... -Tom
