gcc-4.3.3 openoffice-infra

Решил перейти на новый компилятор.
поставил флаги
CFLAGS="-O2 -pipe -march=native -mtune=k8-sse3 -mfpmath=sse -msse3 -m3dnow -minline-stringops-dynamically -momit-leaf-frame-pointer"
USE="mmx sse sse2 sse3 3dnow"

для AMD X2 5600+

запустил emerge -qe @world

Система в общем-то оказалась уже готова к новому компилятору
Один раз пришлось делать --resume для boost boost-build
теперь вот осталось 100 пакетов собрать
среди них офис

 It is important to note that OpenOffice-Infra is a very fragile
 build when it comes to CFLAGS.  A number of flags have already
 been filtered out.  If you experience difficulty merging this
 package and use agressive CFLAGS, lower the CFLAGS and try to
 merge again. Also note that building OOo takes a lot of time and
 hardware ressources: 4-6 GB free diskspace and 256 MB RAM are
 the minimum requirements. If you have less, use openoffice-infra-bin

 Also if you experience a build break, please make sure to retry
 with MAKEOPTS=-j1 before filing a bug.



 If you want the OpenOffice-Infra systray quickstarter to work
 activate the 'gtk' and 'gnome' use flags.

Это что у меня - флаги агрессивные?
так вроде перл умер.
или emerge порядок неправильно построил?

И подскажите пожалуйста флаги такие пойдут или нет
