No, scipy builds on numpy but does not include it. > need scipy.stats I'll have to again install scipy. When I did that using > Synaptic it broke my system. In summary, I don't understand what caused Installing the scipy package will pull in numpy as its dependency, so if you need a newer version of numpy, as you do for mpl, then you also need to remove any packages that depend on it and install them from source. > the problem.

Untar it in some non-system location, maybe a subdirectory of your home directory, and then cd numpy python setup.py build sudo python setup.py install which should install in /usr/local/lib/python2.6/dist-packages. Same drill for scipy and matplotlib. The idea is that synaptic packages get installed in the /usr tree, and anything you install from source gets installed in the /usr/local tree, so they don't get mixed up. > /usr/lib/python2.6/dist-packages/numpy-1.3.0.egg-info.
