You don't need to do this. One installation of Mailman is sufficient for multiple vhosts. I have this running just fine on my site. You have to be willing to patch Mailman/Cgi/admin.py, but this is much cleaner than having multiple copies of Mailman.

1. Create your virtual hosts, if you haven't already. Make sure your vhosts are pointing to Mailman for cgi, icons, and pipermail. For Apache, this is (depending on where ~mailman lives):

ScriptAlias /mailman /usr/home/mailman/cgi-bin
<Directory "/usr/home/mailman/cgi-bin">
  AllowOverride None
  Options None
  Order allow,deny
  Allow from all
</Directory>
Alias /icons /usr/home/mailman/icons
Alias /pipermail /usr/home/mailman/archives/private

This goes inside your <VirtualHost> sections of vhosts.conf for each vhost.

2. In your Mailman/mm_config.py file, make sure that VIRTUAL_HOST_OVERVIEW is set to 1. (I use 2, which is nonstandard, to get an exact vhost match rather than the standard substring match. See patch below. If you have vhost names which are substrings of each other, you will need to use 2 and you will also need to change listinfo.py similarly to admin.py.)

3. Apply the patch below to admin.py. This copies some vhost-discrimination code from listinfo.py to admin.py. It works for 2.0.9 and above (I haven't tried it on older versions.)

4. For each list, change the web_page_url to point to the virtual host. This is the bottom-most parameter on the main admin page for each list. You may need to wait some time for the DNS records of the new vhosts to propagate before people can access the pages.
