Thank you so much for your help. I got it to work!

I found out that I made two errors by testing the script from $PREFIX directory as you suggested. 
One was indentation. The other was the failure to clean up all the newlines when I extracted 
listnames that I wanted to hide from a file (one listname per line).

Here is what I have now:
myfile = '/var/mailman/Mailman/Cgi/notshown'
     noshowns = string.split(open(myfile).read())

     for name in listnames:
         if name in noshowns:
         mlist = MailList.MailList(name, lock=0)
         if mlist.advertised:
             if mm_cfg.VIRTUAL_HOST_OVERVIEW and \
                    mlist.web_page_url.find(hostname) == -1:
                 # List is for different identity of this host - skip it.

Since I need to store a few hundreds listnames in the file, I wonder if it might be better
to use regular expressions.  Five to six regular expressions should be sufficient to match all the
list names I want to hide.

Another option (if it is doable) is to use Mailman's supported advertise feature to hide these
  lists from both listinfo and admin page. I will subsequently bring up a third page, either a
"sub-admin" page showing only those hidden course lists, or a "supper admin" page displaying
all lists.  The goal is that future upgrades won't entail re-customizing the previously customized 
package files.  But I am afraid this may turn out to be so complicated as to involve security 
wrapper and other matters.

I would be very grateful to have your feed back.
