I know the pain having similar trouble to understand the dependencies 
and what is what and why, so any enlightenment towards getting rid of my 
confusion to distinguish what is what and why is highly welcome.

I decided to use numarray, so maybe you can report what your problem/bug 
is before I run into it myself? The reason why I decided to use numarray 
was, that the whole scpy_core story seems to get more or less commercial 
and its free version comes because of this with no documentation of 
newest features.
