It may be possible to solve this problem by using package.mask toprevent one of those packages from being selected. However, it is alsopossible that conflicting dependencies exist such that they areimpossible to satisfy simultaneously. If such a conflict exists inthe dependencies of two different packages, then those packages cannot be installed simultaneously.
For more information, see MASKED PACKAGES section in the emerge manpage or refer to the Gentoo Handbook.

app-text/gnome-doc-utils-0.20.10
是这个包的问题。把它~arch掉升级一下或者干脆删了，再安装你原来的东西

OK了 设定新的use完了后

emerge --update --deep --newuse world 把gcc重新编译了一次 然后
revdep-rebuild 做完这个再把
libxml2给emerge一遍就OK了 估计是我才装完就更新过 忘了些什么东西 现在机器在emerge gnome了 :-) debian用久了 暂时还没习惯过来gentoo的方式

以后再也不买HP的机器了 DEBIAN安装过程中直接黑屏没反应 TEXT界面装完后启动过程中也黑屏 然后自动关了显示器 早上抱着试试看的心情搞个GENTOO上去 还好 一切正常 就是适应过程有点慢

挽，壮哉我大paludis
