按手册安装gentoo后，想安装lamp，apach2已经安装，安装mysql时，提示：

* IMPORTANT: 3 news items need reading for repository 'gentoo'.
* Use eselect news to read news items.


These are the packages that would be merged, in order:

Calculating dependencies  ... done!

emerge: there are no ebuilds built with USE flags to satisfy ">=x11-libs/cairo-1.10.0[-qt4]".
!!! One of the following packages is required to complete your request:
- x11-libs/cairo-1.10.2-r1 (Change USE: -qt4)
(dependency required by "x11-libs/qt-gui-4.6.3-r2" [ebuild])
(dependency required by "dev-util/cmake-2.8.1-r2" [ebuild])
(dependency required by "dev-db/mysql-5.1.51" [ebuild])
(dependency required by "mysql" [argument])
