Aside from that, I'm not sure I have ever really run "emerge

install things left or right to try out either, so typically
upgrades are all I need to do.
You should still run --depclean as dependencies change and you
could still have plenty of no longer needed ones installed.
Okay - so I ran "emerge --depclean -a" and got the below. I tried
running "emerge world -vuDNa" as specified, but that didn't resolve
it either.
I tried looking in the world file (/var/lib/portage/world) but didn't
find any entries that felt safe to remove.
"Safe" as to what? If something is in the world file that you didn't
explicitly request, then it doesn't belong there. For example, if you
have "x11-libs/qt-gui" in world, you should delete it. The world file
should not contain dependencies, it should only contain the stuff you
emerged directly.
To give an example, if you emerge "media-video/smplayer", then that one
will end up in the world file. But smplayer will also pull-in qt and
mplayer. Those do not go in the world file. When you unmerge smplayer
again, qt and mplayer will not be unmerged unless you run "emerge
--depclean". However, if qt and mplayer end up being in the world file
anyway, it means you made a mistake at some point; like emerging
something that is a dependency but forgot to specify the "-1" (or
"--oneshot") option to emerge.
So if you see something in the world file that you know don't need
directly (and I doubt you need qt directly; KDE for example needs it,
you, as a person, don't) it's safe to remove.
Of course always make a backup first :P
