Configure Apache with Ruby on Rails

I'm trying to install Tracks roughly following this guide while trying to configure Apache, but I get the following error when trying to restart Apache:

/etc/init.d/apache2: 1: RailsBaseURI: not found

My current virtual host configuration is:

<VirtualHost *:80>
    ServerName tracks.localhost
    ServerAdmin webmaster@localhost

    DocumentRoot /var/lib/tracks
    <Directory /var/lib/tracks>
        Allow from all
        Options -MultiViews
    </Directory>

    RailsBaseURI /tracks
    <Directory /var/lib/tracks/public>
        Options -MultiViews
    </Directory>
</VirtualHost>

I haven't found many resources where others have encountered the same issue. Does it sound like my Apache passenger installation is bad?

EDIT: If it helps, some additional information on what I've done. I've removed my virtual host configuration and uninstalled the following packages:

sudo apt-get remove libapache2-mod-passenger ruby libopenssl-ruby

and I still get the /etc/init.d/apache2: 1: RailsBaseURI: not found when trying to start Apache. I can't even start Apache now. What the heck does Ruby on Rails do that would cause Apache to not start?!
