It looks like some kind of automagic dependency in libgtop, but I cannot reproduce it.

[Comment 4 Petr Vaněk 2024-09-08 13:56:39 UTC]

Is it possible that portage did not preserve libs back then as it does today?

I am able to reproduce it when I install libXau, than libgtop-2.40.0, which automagically links with libXau.

  emerge x11-libs/libXau
  emerge =gnome-base/libgtop-2.40*

After that I uninstall libXau but I have to remove libXau.so* by hand because emerge preserves it

  emerge -C x11-libs/libXau
  rm /usr/lib64/libXau.so.6*

And now I am able to reproduce it. Anyway, it is indirect app-misc/g15stats issue.
