Comment (by barracuda156):

 It looks like `sys/inotify.h` does not exist on macOS (and nothing
 specific to either PPC or 10.6 of any sort):
 https://gitlab.freedesktop.org/mesa/mesa/-/issues/8101

 However, `kdelibs4` configure detects as if it is, setting this:
 {{{
 //Have include sys/inotify.h
 SYS_INOTIFY_H_FOUND:INTERNAL=1
 }}}

 Which results in usage of those symbols due to related code in
 `kdecore/io/kdirwatch.cpp`.

 Apparently, this happens because something installed `inotify.h` into
 Macports prefix for me. (Quite possible that this was not from existing
 ports, but from something I built locally and did not submit since it was
 not ready yet.)
