一运行emerge app-text/kchmviewer，提示下面的一大堆

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:
dev-libs/libxml2:2
(dev-libs/libxml2-2.9.1-r4::gentoo, ebuild scheduled for merge) pulled in by
dev-libs/libxml2:2[!icu?] required by (dev-qt/qtwebkit-4.8.5::gentoo, ebuild scheduled for merge)
(dev-libs/libxml2-2.9.1-r4::gentoo, installed) pulled in by
dev-libs/libxml2:2/2=[icu] required by (www-client/chromium-35.0.1916.153::gentoo, installed)
dev-libs/libxml2:=[icu] required by (www-client/chromium-35.0.1916.153::gentoo, installed)
It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.
For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.
然后在/etc/portage/package.use里

这些内容都是通过--autounmask-write生成的
大致是因为icu的问题，但是2个软件要求不一样，我应该如何处理？
