mairix problem: "No new messages found" upon initial indexing

[Bill White <billw@wolfram.com>]

Howdy -

I installed mairix yesterday after reading about it in the emacs NEWS
file.  I'm trying to get it to do an initial indexing of my email, but
it won't cooperate.  Here's what it reports:

,----[ shell ]
| [Sun Sep  7 15:37:34 CDT 2008] [billw@billw-desktop ~]$ mairix -v

Here's my config file, based on /usr/share/doc/mairix/dotmairixrc.eg.
"/home/billw/wri/Mail-2006/gunroom" is an nnml dir containing 837
message files and no subdirs; /home/billw/wri/Mail-2006/zzz_mfolder
hasn't been created (should I do that by hand?) and neither has
/home/billw/wri/Mail-2006/mairix_database

,----[ ~/.mairixrc ]
| base=/home/billw/wri/Mail-2006
| maildir=gunroom
| mfolder=zzz_mfolder
| mformat=maildir
| database=/home/billw/wri/Mail-2006/mairix_database
`----

(it's "Mail-2006" because I used to separate my gnus mail into
year-based dirs, and Jan 2006 was the last time I bothered with that)

And here's what I'm using:

 - ubuntu 8.04: Linux version 2.6.24-19-generic (buildd@terranova) (gcc
   version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) #1 SMP Wed Aug 20 22:56:21 UTC
   2008

 - a fresh cvs emacs checkout from yesterday: GNU Emacs 23.0.60.1
   (i686-pc-linux-gnu, GTK+ Version 2.12.9) of 2008-09-06 on
   billw-desktop, compiled via './configure
   --without-toolkit-scroll-bars; make bootstrap'

 - gnus that ships with cvs emacs: Gnus v5.13

 - mairix 0.21, Copyright (C) 2002-2007 Richard P. Curnow, installed
   via 'sudo apt-get install mairix'

Any suggestions?

Thanks -
