REQUISITES

For Debian Etch:

    sudo apt-get install python-dev python-setuptools  
    sudo apt-get install python-imaging
    sudo apt-get install python-psycopg2

For Aaron's PCA
script, I installed MDP from the MDP Toolkit from
<http://downloads.sourceforge.net/mdp-toolkit/MDP-2.2.tar.gz?modtime=1206126105>

Otherwise, I've used only Debian Etch packages: 

- python-scipy        0.5.2-0.1
- python2.4           2.4.4-3
- python2.4-dev       2.4.4-3
- python-imaging      1.1.5-11
- python-psycopg2     2.0.5.1-6
- python-mysqldb      1.2.1-p2-4 (to run with MySQL)
- python-pysqlite1.1  1.1.8a-1 (for unit tests)
- libsqlite3-0        3.3.8-1.1

The sparklines don't look quite as nice with this version of PIL
(python-imaging), perhaps because of `DeprecationWarning: integer
argument expected, got float: self.draw.draw_lines(xy, ink, width)`.
watchdog.net is running PIL 1.1.6-1.
