Comment (by nicos@…):

 Replying to [comment:6 rjvbertin@…]:
 > I'd agree with that were it not that there are probably enough KDE ports
 that do not really require a kbuildsycoca4 invocation.
 Well, at least all the ones making any use of plugins, which should not be
 negligible. As it would be cumbersome to track each port, the simplest
 should be to consider this a general issue in my point of view. And since
 the command builds a binary database, it still should be run each time
 something new is installed to maintain the database up to date.

 > In fact, one could also argue that the message need appear only when
 installing the base KDE ports, because once those are installed the OS
 takes care of loading the required agent(s). At least that's how it seems
 to work on my 10.6.8 system (and I'd better not try to launchctl unload
 them because the commands shown in the note don't seem to be enough to
 restore KDE functionality after that). 10.9 may indeed be different and
 require a manual launchctl load of at least the dbus agent.
 That is the current state, with the message appearing at activation of
 kdelibs4, but not for the reason you state. The system does not in
 principle load agents without explicitely asking for it. That is true in
 particular for the one we talk about, as it must be run at user (and not
 root) level.

 > In short, I'm not sure if it's useful to clutter the output when
 installing/upgrading all KDE packages with this note. One could think of a
 more terse message reminding only to execute kbuildsycoca4 by hand if a
 newly installed port seems to lack functionality like I had with digikam.
 > Is it possible to display such a note only after a new install, and not
 after an upgrade (supposing an upgrade doesn't introduce new components or
 suppress existing ones)?
 I do not know of any way to differentiate between install and upgrade at
 Portfile level. But as this would imply further complication by tracking
 possible changes, I would keep the current policy of the provided agent,
 which is to always run it just in case.
