poudriere jail stable/0 create via svn: auditdistd user is missing

[Patrick Lamaiziere]

Hello,

# poudriere jail -c -j 9amd64 -v stable/9 -m svn
...
--------------------------------------------------------------
>>> World build completed on Wed Jan  9 01:32:43 CET 2013

====>> Starting make installworld
ERROR: Required auditdistd user is missing, see /usr/src/UPDATING.
*** Error code 1

*** Error code 1

Stop in /poudriere/jails/9amd64/usr/src.
====>> Error: Fail to install world
====>> Error while creating jail, cleaning up.
====>> Removing 9amd64 jail...done

Any idea to work-around this (in a normal buildworld I would use
mergesmaster -p) ? I'm using an old 9-stable from april.

Thanks, regards.
