It begs the question who/what could have changed the root group membership to 
include the system account 'man'.  This is highly irregular.  Have you looked 
at your backups to find out when /etc/group was changed last time?  Also 
emerge.log to find the last time acct-user/man was installed successfully 
before this error started occurring.
