I haven't followed this discussion in great detail, but I believe the current
situation is this:

1) If you use numpy.dft and numpy.linalg directly, you will always get the numpy
versions no matter what else is installed.

2) If you want to optionally use optimized scipy versions if they are available
and regular numpy versions otherwise, then you use the functions exposed in
numpy.dual. You do so at your own risk.

3) pkgload() exists to support the loading of subpackages. It does not reach
into numpy.dft or numpy.linalg at all. It is not relevant to this issue.

4) There are some places in numpy that use numpy.dual.

I think we can address all of your concerns by changing #4.
