In fact, from your log messages, it is clear that the agent is loaded, as it is run from org.macports.kdecache. I did not look closely before.

True. It may be possible to solve it by clearing the kdecache folder and running kbuildsycoca4 manually once, even though I am not fully clear about the errors.

It is possible by editing the file in /Library/LaunchAgents/org.macports.kdecache.plist and setting the key

    <key>ThrottleInterval</key>
        <integer>60</integer>

to the desired amount of seconds. It may be necessary to reload the agent for the change to be effective. Furthermore, this is partly a hack, in the sense that an upgrade of kdelibs4 would overwrite the change. 

However, if these types of issues appear, I may have to consider changing the interval also in the portfile.
