I'm trying to get a new installation of mailman running on a new 
installation of apache.  Both were installed via pkgsrc.  When I try to 
use a mailing list, however, I get a message saying

	WANTED gid 31, GOT gid 39.

In other words, mailman was configured to expect gid 'guest', while 
apache was running CGIs under gid 'nobody'.  Is this a problem with the 
default installation of one or the other, most likely mailman?  If not, 
what is the cleanest way to reconfigure one or the other to solve the 
problem?
