$ bittorrent

A BitTorrent package for the wrong version of Python is installed on this
system.  The default version of Python on this system is 2.4.  However, the
BitTorrent package is installed under Python 2.4.

        To install BitTorrent correctly you must first:

        * Remove *all* versions of BitTorrent currently installed.

        Then, you have two options:

        * Download and install the .deb or .rpm package for
          BitTorrent & Python 2.4
        * Download the source .tar.gz and follow the directions for
          installing under Python 2.4
