[Mailman-Users] Snafu'd config

[Stephen E. Hargrove]

I've just installed mailman, and have apparently configured something
incorrectly.  I've looked, but I'm just not seeing it.

The welcome email sent to me by the system pointed me to
http://whatever/mailman/admin/listname.  I entered my password, and thes
page opened fine.  I made a few changes and hit the Submit Your Changes
button.  I'm then given the following:

The requested URL /admin/listname was not found on this server.

It should probably be pointing to /mailman/admin rather than /admin. 
Any ideas what I may have configured incorrectly?

Thanks!
