Here it is:

VAR_PREFIX      = '/var/spool/mailman'

The data directory existed.  I only 'touch'ed /var/spool/mailman/data/aliases.

IOError: [Errno 13] Permission denied: '/var/spool/mailman/data/aliases'

$ ls -lh /var/spool/mailman/data/aliases
-rw-r--r--  1 root      _mailman     0B Mar 20 14:31 aliases

$ chmod 660 /var/spool/mailman/data/aliases

Then I created another list via the interface and no error!

However, I did get a postfix error since I had not put in the new aliases file 
path.  After doing that and reloading postfix I created another list.  
Everything was ok except I get the Group mismatch error again.

Guess I need to remove the package and install the port.
