Hmm, is that because the build process looks for existing codecs in 

I can't take down Mailman while I build the new version - it takes too 
long, and Mailman is too important for our business. And, I don't work 

Similarly, I can't mess with the current installation in order to make the 
new one build. I have to make a new build, test it, then deploy it. If 
deployment takes a couple of minutes to take down the service, move some 
links, then bring it back up, that's OK.

Actually, that raises an issue. When I install Python, it kindly installs 
in eg /local/lib/python2.4 - then it moves a link to enable the new 

It would be very nice if Mailman would do the same. Taking down my list 
server while building the new one isn't practical. Especially when I can't 
be sure the new one will work. I found I have to:
    build (configure, make, make install) with <prefix> = 
    test the web pages (fixing apache config to find the cgi)
    configure with <prefix> = /local/mailman
    hack the Makefile to install in /local/mailman-2.1.6
    make, make install
    link archive, log, queue directories
    take down mailman
    link /local/mailman
    put mailman back up

Now, this process is kind of workable, but has these drawbacks:
    1. it's more complex than it should be
    2. I never get to test what I finally install - it has to be rebuilt
    3. It takes much longer than it should.

Ah, well that'll have to wait, I'm afraid. I've downgraded Python to 2.2.3, 
and reinstalled Mailman. Seems to work just fine. We don't use Python for 
much else, so I'm not desperate to update it.
