When installing (from source), pick a different base installation and a
different user/group for the install to use. You do this by adding some
switches the  "./configure" command:

    --prefix=<dir>
          Standard GNU configure option which changes the base
          directory that Mailman is installed into.  By default
          $prefix is /usr/local/mailman.  This directory must
          already exist,

    --with-username=<username-or-uid>
          Specify a different username than `mailman' to use as a
          default.  Use this only if the username `mailman' is
          already in use by somebody (e.g. Mark Ailman's login
          name).  This switch can take an integer user id or a user
          name.  Be sure your $prefix directory is owned by this
          user.
 
    --with-groupname=<groupname-or-gid>
          Specify a different groupname than `mailman' to use as a
          default.  Use this only if the groupname `mailman' is
          already in use.  This switch can take an integer group id
          or a group name.  Be sure your $prefix directory is
          group-owned by this group.

Using this, you can install any number of Mailman instances on one
server; all using the same local web-server and the same local
mail-server.

You'll need to have separate settings inside your httpd.conf file for
each installation of mailman:

#  httpd configuration settings for use with mailman.
#
 
ScriptAlias /mailman/ /usr/local/mailman/cgi-bin/
Alias /pipermail/ /usr/local/mailman/archives/public/
<Directory /usr/local/mailman/archives>
        Options +FollowSymlinks
</Directory>
#
#  httpd configuration settings for use with mailman2.
#
 
ScriptAlias /mailman2/ /usr/local/mailman2/cgi-bin/
Alias /pipermail/ /usr/local/mailman2/archives/public/
<Directory /usr/local/mailman2/archives>
        Options +FollowSymlinks
</Directory>
#
# etc...
