emerge: there are no ebuilds built with USE flags to satisfy "sys-auth/pambase[consolekit]".
!!! One of the following packages is required to complete your request:
- sys-auth/pambase-20090620.1 (Change USE: +consolekit)

localhost ~ # emerge -av --depclean

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

* Dependencies could not be completely resolved due to
* the following required packages not being installed:
*
* virtual/libusb:0 pulled in by:
* sys-apps/usbutils-0.73
*
* 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`.

是怎么回事，帮帮我，
谢谢。。。

到明天 emerge --sync 應該就好，如果不要等，也可以用emerge-webrsync下個穩定點的。另外就是如果你有自己搞的Overlay而不是用layman管理的話，把你自己的Overlay先撤下。
　　另外就是在/etc/portage/package.use中設置一下sys-auth/pambase consolekit，以完成安裝。
　　提醒你一下，用eselect news read all看下官方的信息。
　　感覺你至少是從stage2開始安裝，或者是想試試新的gcc了。祝你之後一切順利。
