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.

你的make.conf里估计有全局的+qt4
在/etc/portage/package.use 加上-qt4

参看:

2. media-libs/opencv gtk ffmpeg v4 -qt4

后面一个问题。。。还是看手册去吧
