[Mailman-Users] configuration problem

Installing on debian testing, all packages up to date.

Ok, it complicated maintenance a bit too much in my net to dedicate an
IP address to lists.domain, so I thought I would try the exact
approach as detailed in the install manual with postfix, namely using
alias_maps and virtual_alias_domains, etc., leading to a postfix
main.cf containing:

# http://www.postfix.org/ADDRESS_REWRITING_README.html#masquerade
masquerade_domains = lists.pinyon.org pinyon.org
# http://www.postfix.org/virtual.5.html
virtual_alias_domains = lists.pinyon.org
virtual_alias_maps = hash:/var/lib/mailman/data/virtual-mailman

alias_maps = hash:/etc/aliases hash:/var/lib/mailman/data/aliases
alias_database = hash:/etc/aliases

And that worked great!  Using the suggested initial 'mailman' list
I was able to add subscribers and send/receive, etc.  Perfect.

I ran into a permissions problem with apache and the private archives,
so I thought I would stop at that point, purge the installation, and
carefully recreate the configuration from scratch so that I could
document the exact steps for mailman installation on my site properly.

So I do (leaving the postfix previously working main.cf untouched):

$ apt-get remove --purge mailman
$ /bin/rm -rf /var/lib/mailman /usr/lib/mailman
$ cp [my-saved-working-copy-of-mm_cfg.py] /etc/mailman
$ newlist mailman
  [exact same stuff as before]
$ /etc/init.d/mailman start
$ /var/lib/mailman/bin/genaliases
$ /var/lib/mailman/bin/check_perms -f

and I notice that:

$  ls -lt /var/lib/mailman/data
total 36
-rw-rw---- 1 root list  1132 Jan 26 18:06 aliases
-rw-r----- 1 root list 12288 Jan 26 18:06 aliases.db
-rw-rw-r-- 1 root list    10 Jan 26 18:04 last_mailman_version
-rw-r--r-- 1 root list 14100 Oct 21 22:40 sitelist.cfg

Ok, first problem.  Where's virtual-mailman (and virtual-mailman.db)?

I go to the web interface http://lists.pinyon.org, but there is
no 'mailman' list.  I try to create the 'mailman' list in the web
interface, and I get:

Error: List already exists: mailman

So... what should I do?

Many thanks,
