Numpy 0.9.8 is easy_install'able with the latest setuptools (0.6b1). I
just tried, and scipy bombs out partway (looks like it doesn't build
the fftpack library, so I'm guessing somewhere some
dependency-generating code doesn't get called).

The problem is we extend distutils (with numpy.distutils) extensively,
and some of that conflicts with what setuptools does, so using
easy_install is a bit fragile. (The current "fix" depends on some
internal details of setuptools, hence the requirement for 0.6b1.)

Making an egg is ok, and has worked for a while now. Do this:

$ python setup.py build
$ python -c 'import setuptools; execfile("setup.py")' bdist_egg
$ easy_install dist/scipy-<version>.egg
