Проблема сборки KDE 4

Вобщем решил поставить сабж...
При сборке kde-base/kdebase-4.0.0 выпало:
------------------------------------------------------------------------------------------------------------

еще пишет такую вещь:
`-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead.
но
CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer"
CXXFlAGS="${CFLAGS}"

Где ж грабли?????????
