Calculating dependencies... done!

Dependencies could not be completely resolved due to
the following required packages not being installed:

>=virtual/perl-Compress-Zlib-1.14 required by dev-perl/Archive-Zip-1.23
virtual/perl-ExtUtils-CBuilder required by perl-core/File-Spec-3.27.01

Have you forgotten to run `emerge --update --newuse --deep world` prior to
depclean?  It may be necessary to manually uninstall packages that no longer
exist in the portage tree since it may not be possible to satisfy their
dependencies.  Also, be aware of the --with-bdeps option that is documented
in `man emerge`.

In running emerge --update --newuse --deep world, it yields nothing.

msoulier@anton:~$ sudo emerge --update --newuse --deep world
Calculating world dependencies... done!
>>> Auto-cleaning packages...

>>> No outdated packages were found on your system.


What would you recommend I do here?

Did you try emerge --update --newuse --deep --with-bdeps=y world
as hinted at by the above msg?

Yep, I had to add that option to mine a while back for --depclean to
work. Add that and it should run cleanly afterwards. You could also
--oneshot those in the list and it should work. I haven't tried that yet
but read it works.

The docs on this seem wrong. 

       --with-bdeps < y | n >
              In dependency calculations, pull in build time dependencies that
              are  not strictly required.   This defaults to 'n' for installa-
              tion actions and 'y' for the --depclean  action.   This  setting
              can be added to EMERGE_DEFAULT_OPTS (see make.conf(5)) and later
              overridden via the command line.

But it doesn't seem to default to y for --depclean. I get completely different
results when I set --with-bdeps=y on --depclean.

And yet they're not, since this is an update and not a depclean. I'll be quiet
now.

Try this command:

emerge --update --newuse --deep --with-bdeps y world

When that is done, then try the --depclean, with a -p first.  ;-)
