проблема после обновления portage

ставлю систему на машину с диска 2005.1 stage3-pentium4 portage-20060927 ядро 2.6.18 профиль 2006.1/desktop - вся установка без проходит проблем
перегружаюсь, вхожу систему - тоже все нормально
emerge -pv system выдает 65 пакетов которые надо обновить, все они есть в дистах
среди всех обновить portage до 2.1.2_pre1-r4
emerge system
пакеты до portage ставять нормально, сам portage тоже ставить, но вот после него:
