That's not much ;)

Ah, thanks, didn't know that one.

I guess I just have too many little stuff in @world. E.g. I explicitly
want the x265 commandline tool, so I have media-libs/x265 in @world.
Same goes for e.g. ffmpeg (for /usr/bin/ffmpeg), etc. pp. Or just
this:

# grep -c app-arch/ /var/lib/portage/world
42      (sic! ;)

Lots of app-{x,}emacs/, app-shells/, app-portage/, app-text/,
games-*/, media-*/...

I'm reather overeager emerging with -1 :) Hah! Got one: --depclean
suggested dev-haskell/x509-validation. Ok, removed it and it is still
used. Ok, let's see if rebuilding depending stuff
(dev-haskell/connection and dev-haskell/tls) helps:

Doesn't seem like it:

 * ghc-pkg check: 'checking for other broken packages:'
There are problems in package connection-0.2.5:
  dependency "x509-validation-1.6.5-9d1Itw2kfW6JXBlF0ahQsB" doesn't exist
There are problems in package tls-1.3.9:
  dependency "x509-validation-1.6.5-9d1Itw2kfW6JXBlF0ahQsB" doesn't exist
[..]
>>> Failed to emerge dev-haskell/connection-0.2.5,

So, remerging dev-haskell/x509-validation. That's one example of the
"overeager" --depclean... (and no, neither dev-haskell/connection
dev-haskell/tls has the "profile"-USE-flags set, but it seems the
build does actually need it).

Whoa, --depclean wants to remove a bunch of eselects too, e.g.
app-eselect/eselect-package-manager and app-eselect/eselect-pdftex.
Ok, I don't have texlive-core in world, but it is pulled in by various
other stuff...

Oh well, I'll have to check what depclean's doing wrong better.
