[gentoo-alt] [AIX] emerge fails on wheelgid

[Marshall McMullen]

I had been working on this issue with Fabian a while back: http://www.mail-archive.com/gentoo-alt@l.g.o/msg02965.html 

But there was never any resolution as to what might be causing this problem and I had since given up. But, now I have renewed reason for getting this to work, so I would really appreciate some help in figuring out what is going on. For the system I am using, I do not have a local account or group on, only LDAP accounts. 

Essentially emerging any fails as follows: 

emerge --oneshot "=sys-apps/sed-4.1.4*" 

portage: mdmcmull user or p/gnu/admin group missing. 
In Prefix Portage this is quite dramatic 
since it means you have thrown away yourself. 
Re-add yourself or re-bootstrap Gentoo Prefix.

Fabian had asked me to run these commands: 

python -c 'import pwd; print(pwd.getpwall())' | grep mdmcmull 
This does not produce any output, nor does: 

python -c 'import grp; print(grp.getgrall())' | grep mdmcmull 
It seems the pwd and grp modules only query the local Unix /etc/passwd and /etc/group files. Can anyone confirm that ? 

In any event, I would appreciate any advice or help in getting this to work. 

Thanks, 
Marshall
