Me, I use eggs. One advantage is, since I use the bleeding edge for
for all of my code, if there's something wrong with numpy (or scipy) and I
don't have the time to fix it, I can switch to an older version.

I've got a make-egg script that looks like

set -e

${PYTHON} setup.py build
${PYTHON} -c 'import setuptools; execfile("setup.py")' bdist_egg

then easy_install2.4 dist/<egg file>
