No, even worse!  Here's what I do, and what happens:

Add folders with the names of the subdomains.
Add SiteRoots to each of these folders, with both fields blank as
instructed.
Create a dtml-method at the root level named "virtualhosts" using the
script you provided.
Add a Site Access Rule at the root level linked to the method.
... everything works fine up to here.  A confirmation message appears
saying "You have added a site access rule" or something like that.  Then
when I click on "OK", a dialog comes up saying "Authorization failed,
retry?".  Even the superuser doesn't work.  I try quitting the browser
(Netscape) and accessing the site (using any of the urls -
masspirg.penguinpowered.com, singlepayermass.penguinpowered.com, others),
but the exact same error occurs.  Here is the traceback:

Let me clarify some relevant things about my setup.  My server is in my
dorm room, thus is allocated a dynamic IP address through DHCP, also a
random hostname (prin-###.res.umass.edu).  I get around this by
registering some names with penguinpowered.com "dynamic DNS" and
automatically updating them with my IP address when it changes.  Before I
tried this virtual hosts experiment, the system worked just fine -
everyone who tested it could reach masspirg.penguinpowered.com.  I'm
teaching myself this server/content management stuff during this summer as
I work on a groupware-like site that will eventually be moved to a
dedicated server with a better connection.

Thanks for all your help - I'm sure you have much more important things to
do than assisting newbies like myself!
