Установка KDE

да

народ вы ппц
kdetoys, kdeedu, kdewebdev, kdegames - это пакеты никак не свзанные с kdebase
Вот что надо (примерно):
emerge kdebase kdepim kdeutils и т.д
А вообще в доках про граф. среду есть руководство по кедам (лучше читай английскую версию)

КДЕ в Генте можно собрать несколькими способами. Первый и самый логичный - emerge kde и идти спать. Вот тут поставится все, и kdegames, и kdepim, и прочее. Это т.н. монолитная сборка. Второй способ - сборка модульная. для чего делается emerge kdebase-startkde, который почти все необходимое для корректного старта кедов подтягивает зависимостями. Дальше устанавливается только нужный вам софт.
