40 Ok, at least you can update the FAQ now, by doing copy&paste from your
41 answer :D
42 The reason why I did such mistake with x86 profile on the amd64 pc is
43 because I
44 used the buggy 2006.0 LiveCD to install Gentoo just to save my time.
45 You're right,
46 I'm Gentoo-newbie, I am from Debian world, I just gave another try to
47 Gentoo.

49 I will fall back to x86 profile, thank you.
