I know that this has been going around the internet lately.  I've done 
the usual web search.  Not really found anything that might work for 
me.  I've installed a CentOS 7 web server.  I'm building a site around 
it. Mailman is my list management software.  I've used it for more 
than ten years.  Would like to keep using it.  

After installing the standard CentOS 7 package with yum I did..... 'cd 
/usr/lib/mailman' and 'bin/update'.  This installed Mailman 2.1.15. 
Which then told me after 'service mailman start' ...

" Bug in Mailman version 2.1.15. We're sorry, we hit a bug!
Please inform the webmaster for this site of this problem. Printing of 
traceback and other system information has been explicitly inhibited, 
but the webmaster can find this information in the Mailman error logs. 

Alright.  So, I've stopped knocking my head against the desk now.

Can anyone make a suggestion as to how to get this to work for me ?  
Perhaps I can just completely remove mailman and reinstall from the 
default CentOS 7 package ?  Is there a downgrade option so that I 
could fix it that way ?
