Problem doing self update on MacPorts version 2.3.4

[list_email at icloud.com]

Trying to do selfupdate and had the following problem. Using Version 2.3.4, hoping to upgrade.

Is this a permissions problem on /opt? If so, what should the permissions be? I prefer changing permissions with Finder or Path Finder.

Many thanks as always,
Jerry
