[Mailman-Users] Group name "mailman" doesn't exist

[Shawn Wilson]

I'm trying to get mailman up and running on my Gentoo box alongside 
postfix but I can't seem to get over this final hurdle. Here is what I 
get in my log when I try sending a message to one of my lists:

=== BEGIN LOG ===
Dec  1 15:47:28 jupiter2 postfix/smtpd[19851]: 70D562C82A1:

(Command died with status 8: "/usr/local/mailman/mail/mailman post 
kilimanjaro". Command output: Failure to find group name mailman.  Try 
adding this group to your system, or re-run configure, providing an 
existing group name with the command line option --with-mail-gid. )
Dec  1 15:47:28 jupiter2 postfix/qmgr[1027]: 70D562C82A1: removed
=== END LOG ===

The pertinent part is "Failure to find group name mailman". However I 
know that this group exists:

    $ grep mailman /etc/group
    mailman::280:

As you can see, group "mailman" exists with ID 280. I checked my ebuild 
file for mailman and MAILGID is indeed set to 280, which means it should 
be passing --with-mail-gid=280 to the configure script. I have run 
check_perms and all permissions look okay.

Any ideas what else I can do to figure out what went wrong? I posted 
this request on the gentoo forums as well but so far the couple replies 
I received have not helped.

Thanks,
