GENTOO 安装 FCITX比较简单，

Install source

Fcitx has been in Gentoo portage tree for a long time. You can install it using emerge.

# emerge -av fcitx

It is strongly recommended to add the gtk, gtk3, qt USE flags in order to build the corresponding im modules.

# USE="gtk gtk3 qt4" emerge -av fcitx

Or you can add the USE flags in /etc/portage/package.use and then install it. (recommended)
