It looks like you are trying to use code that was described here:

    http://mail.scipy.org/pipermail/scipy-dev/2009-March/011682.html

That email describes a proposed addition to scipy, but that is not the API
that we ended up with.  For the wavelet functions in scipy, see
http://docs.scipy.org/doc/scipy/reference/signal.html#wavelets
