emerge depclean 提示的信息，怎么解决

gentoo ~ # emerge depclean
*** Deprecated use of action 'depclean', use '--depclean' instead

*** WARNING ***  Depclean may break link level dependencies.  Thus, it is
*** WARNING ***  recommended to use a tool such as `revdep-rebuild` (from
*** WARNING ***  app-portage/gentoolkit) in order to detect such breakage.
*** WARNING ***  
*** WARNING ***  Also study the list of packages to be cleaned for any obvious
*** WARNING ***  mistakes. Packages that are part of the world set will always
*** WARNING ***  be kept.  They can be manually added to this set with
*** WARNING ***  `emerge --noreplace <atom>`.  Packages that are listed in
*** WARNING ***  package.provided (see portage(5)) will be removed by
*** WARNING ***  depclean, even if they are part of the world set.
*** WARNING ***  
*** WARNING ***  As a safety measure, depclean will not remove any packages
*** WARNING ***  unless *all* required dependencies have been resolved.  As a
*** WARNING ***  consequence, it is often necessary to run
*** WARNING ***  `emerge --update --newuse --deep world` prior to depclean.

Calculating dependencies... done!

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

~perl-core/Test-Simple-0.64 required by virtual/perl-Test-Simple-0.64 dev-perl/Net-DNS-0.53-r1
~perl-core/digest-base-1.13 required by dev-perl/Digest-SHA1-2.11 virtual/perl-digest-base-1.13 dev-perl/Digest-HMAC-1.01-r1

Have you forgotten to run `emerge --update --newuse --deep world` prior to
depclean?  It may also be necessary to manually uninstalled packages that no
longer exist in the portage tree since it may not be possible to satisfy their
dependencies.


* GNU info directory index is up-to-date.

Have you forgotten to run `emerge --update --newuse --deep world` prior to depclean?
这不是告诉你了么？
另外请运行emerge --depclean，而不是depclean
