How to fix a broken owner for files from world & build from ports?

[Ralf Mardorf]

Hi :)

I hope it's ok, when I open a new thread for this issue.
First I need to know what files have a bad owner.

I'm running
# freebsd-update IDS >> outfile_28Jan2013.ids
perhaps this will give some useful output, regarding to a wrong owner for  
files from world.

It's still running.

I still have no idea how to check this for the files build from ports.

Regards,
Ralf
