Sudo: needed?

[Eneko Gotzon Ares]

Good morning magnanimous techies!

Upgrading kdelibs4 port this note is displayed:
# An agent to provide communication between KDE programs must be  
started.
# To start it run the following command:
# launchctl load -w /Library/LaunchAgents/org.macports.kdecache.plist

That command:
·Must be preceded by a "sudo" code? (i.e., sudo launchctl load -w / 
Library/LaunchAgents/org.macports.kdecache.plist).
·When that "sudo" code is needed, the messages of the Terminal always  
express it explicitly?

Thank you very much!
