Hello, I'm trying to install a campware news publishing system
I've uploaded the files as it was said in the install manual. but I get an error

Code:
Warning:  main(/home/videoxon/public_html/include/campsite_init.php) [function.main]: failed to open stream: No such file or directory in /home/videoxon/public_html/newspub/index.php on line 24

Fatal error:  main() [function.require]: Failed opening required '/home/videoxon/public_html/include/campsite_init.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/videoxon/public_html/newspub/index.php on line 24
This is the install manual;

PREPARATION - applications you need to have installed
  see the manual page at:
  http://code.campware.org/manuals/campsite/2.7/index.php?id=5

INSTALLATION - the usual procedure

1. Create an apache virtual host.
Example of virtual host configuration:
<VirtualHost *>
    DocumentRoot /var/www/campsite/html
    ScriptAlias /cgi-bin/ /var/www/campsite/cgi-bin/
    ServerName [site_name]
    ServerAlias [site_alias]
    DirectoryIndex index.php index.html
    <Directory /var/www/campsite/html>
            Options -Indexes FollowSymLinks MultiViews
            AllowOverride All
            <IfModule mod_access.c>
                Order allow,deny
                Allow from all
            </IfModule>
    </Directory>
    <Directory /var/www/campsite/cgi-bin>
        AllowOverride All
        Options ExecCGI
        <IfModule mod_access.c>
            Order allow,deny
            Allow from all
        </IfModule>
    </Directory>
</VirtualHost>

2. Unzip and Untar the campsite file. This will generate a
   folder named 'campsite'.

3. Change into the 'campsite' directory.

4. Copy the content of implementation/site directory into the document
root directory of the apache virtual host.

5. Start a browser, point it to the http://site_name URL and follow the
steps.

6. To install the default demo templates provided with the package take
the following steps:
    - copy the content of demo templates directory to "templates"
    directory in the document root; the sample templates are located in:
    [document_root]/install/sample_templates/campsite_3.0-sample-template-01-v1

    - drop the just installed database (e.g. campsite)

    - create an empty database (campsite)

    - load the demo data to campsite from
    [document_root]/install/sql/campsite_3_0_demo_data.sql

INSTALLATION of multiple instances

Since version 3.0 Campsite doesn't support multiple instances anymore.
You will have to perform one install for each Campsite instance.
Maybe someone can point out something I've missed? I don't quite understand the first point of "creating a virtual host". I've just uploaded everything to my server like I usually do.
