在 Gentoo 上 Emerge 失败，并显示“单个包槽中的多个包实例已被拉入……”。我该如何解决这个问题？

Question

我正在尝试在我最近的 Gentoo 盒子上安装 Google Chrome。但是emerge抛出了一些我无法理解的错误。我真的不知道问题是什么。

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

dev-libs/glib:2

  (dev-libs/glib-2.32.4-r1::gentoo, installed) pulled in by
    <dev-libs/glib-2.33:2 required by (dev-libs/gobject-introspection-1.32.1::gentoo, installed)

  (dev-libs/glib-2.36.4-r1::gentoo, ebuild scheduled for merge) pulled in by
    >=dev-libs/glib-2.34.0:2 required by (x11-libs/gdk-pixbuf-2.28.2::gentoo, ebuild scheduled for merge)
    (and 2 more with the same problem)

media-libs/fontconfig:1.0

  (media-libs/fontconfig-2.8.0-r1::gentoo, installed) pulled in by
    (no parents that aren't satisfied by other packages in this slot)

  (media-libs/fontconfig-2.10.92::gentoo, ebuild scheduled for merge) pulled in by
    >=media-libs/fontconfig-2.10.91:1.0= required by (x11-libs/pango-1.34.1::gentoo, ebuild scheduled for merge)

我已经按照输出中的建议尝试了--backtrack=30和--autounmask-write选项，但输出没有区别。

我只需要知道问题是什么才能找到解决方案。任何帮助是极大的赞赏。

这是由于系统过时造成的。所以更新它解决了这个问题： emerge --update --deep --with-bdeps=y --newuse @world
