apache configuration for cohosting mod_python and php based apps

I have django+python+apache2+mod_python installed hosted and working on ubuntu server/ linode VPS. php5 is installed and configured. We don't have a domain name as in example.com. Just IP address. So my apache .conf file looks like this

ServerAdmin webmaster@localhost DocumentRoot /var/www

        SetHandler python-program
        PythonHandler django.core.handlers.modpython
        SetEnv DJANGO_SETTINGS_MODULE mysite.settings

        PythonOption django.root /mysite
        PythonPath "['/var/www/djangoprojects',] + sys.path"
        PythonDebug On

I want to install vtiger so if I change my .conf file like say this

DocumentRoot /var/www/vtigercrm/

ErrorLog /var/log/apache2/vtiger.error_log
CustomLog /var/log/apache2/vtiger.access_log combined

    Options Indexes FollowSymLinks MultiViews
    AllowOverride None
    Order allow,deny
    allow from all

This way vtiger the php based app works fine and ofcourse django app is not accessible. How do I make both co-exist in one file. i cannot use virtual host/subdomains. I can do with a diff port no thou.

Any clue guys ?
