There are binary PyLucene 1.9.1 Debian Stable (Sarge)
packages for the i386, amd64, and powerpc architectures.
To install PyLucene add the following apt repository to
your /etc/apt/sources.list file:

    deb http://www.canonical.org/debian/ sarge main

then run the following commands:

    apt-get update
    apt-get install python2.4-pylucene

PyLucene only works with Python 2.4 so to make use of it
ensure you are using /usr/bin/python2.4 and not /usr/bin/python.
