Yes, that's what I found out and am doing now.

That's the bug in the configuration example.

What it still not working is the handling of the $BOGOFILTER_DIR 
environment. The manual says:

ENVIRONMENT
        Bogofilter uses a database directory, which can be set in the config
        file. If not set there, bogofilter will use the value of
        BOGOFILTER_DIR. Both can be overridden by the -d dir option. If none of
        that is available, bogofilter will use directory $HOME/.bogofilter.

This should also work when I export 
$BOGOFILTER_DIR=/some/location
in my shell rcfile, but it doesn't.
