emerge--depclean

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

=sys-libs/libstdc++-v3-3.3* required by dev-java/sun-jdk-1.6.0.01 virtual/libstdc++-3.3

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`.

 * GNU info directory index is up-to-date.
 * IMPORTANT: 38 config files in '/etc' need updating.
 * Type emerge --help config to learn how to update config files.
