Macports taking over file permissions on Time Machine files

Description

Trying to access files from my old Time Machine backups, I noticed I don't have permissions to open many of the folders (e.g. Users, System, etc)

Here is a dir listing (below), and anything owned by macports:staff is neither accessible by sudo user nor can be changed by chown or chmod commands...

Any idea how to modify permissions so I can get access? Thanks!

I think I found a solution myself... This is ACL issue: 

drwx------+

where '+' sign indicates ACL dependency.

I ran 

cd /Volumes/Toshi/Backups.backupdb/
chmod -RN vostok

to rid of ACL and voila:

Still unsure how MacPorts hijacked my permissions, but chmod -RN did the trick!

MacPorts does not hijack permissions or ownership. MacPorts creates a normal system user account—"macports"—and uses it for certain purposes.
