11 You have to make a symbolic link, /etc/make.profile, to a particular
12 profile in /usr/share/portage/profiles, i.e. either the multilib (64/32)
13 or the no-multilib (64-bit) profile. Also, the USE flag "multilib"
14 indicates to the compiler that both 32-bit and 64-bit libraries should
15 be built.
17 Check the Gentoo manual for all the details. You'd best get used to
18 reading the manual early. Everything is in there.

24 I'm not sure. It's best to check the manual.
