You will also want to remove the f2py package and its script as
scipy.f2py replaces it. weave, too, although that is less likely to get
in the way.

No, that's still the old scipy. The new scipy_core and scipy in general
are being developed on branches at the moment. As has been explained in
the various announcement emails:

# for scipy_core:
svn co http://svn.scipy.org/svn/scipy_core/branches/newcore/
cd newcore
python setup.py install
cd ..

# for the new scipy:
svn co http://svn.scipy.org/svn/scipy/branches/newscipy/

We are in the process of porting the rest of scipy to the new
scipy_core, so the latter tree doesn't build anything useful, yet.
Contributions are welcome. In another email, Pearu has briefly outlined
some basic information one needs to know about the new scipy.distutils,
and there's more documentation on its way. There is a file TOCHANGE.txt
that contains a list of things that need to be done to complete the port.
