>Multilib is now forced on in the base 2005.0 profile. If you wish to have a pure-64bit system, you can use the 2005.0/no-multilib profile. This guide will show you how to upgrade a prior installation to a system that uses our new profile. There are two ways of upgrading: the easy and scripted way, or the longer way by hand.
>
>
>2005.0 hasn't been released yet, so there are still some changes you will need to make in /etc/portage to get this process to work:
>

># echo '=app-emulation/emul-linux-x86-glibc-2.3.4.20041102 ~amd64' >> /etc/portage/package.keywords
># echo '>=sys-kernel/linux-headers-2.6' >> /etc/portage/package.unmask

>If you currently have USE=-multilib, you need to set multilib in USE and re-emerge gcc. 
>
><pre>
># nano /etc/make.conf
><codenote>remove -mutilib from USE flags</codenote>
>
># emerge gcc
><codenote>If youu get an error about not having a multilib sandbox, you need to set FEATURES=-sandbox</codenote>
># FEATURES=-sandbox emerge gcc
></pre>
>
>Additionally, you need to make sure you have the required versions of toolchain/portage packages as these are needed to properly rebuild glibc after switching the profile.
>
><pre>
># emerge -v --oneshot '>=sys-apps/portage-2.0.51-r9'
># emerge -v --oneshot '>=sys-devel/gcc-config-1.3.9'
># emerge -v --oneshot '>=sys-devel/distcc-2.18.3-r1'
># emerge unmerge linux26-headers
># emerge -v --oneshot '>=linux-headers-2.6.8.1-r4'
></pre>
>
>Next, make sure our 32bit glibc version is up to date. This version is needed to bootstrap the 32bit glibc build after the profile switch.
>
><pre>
># emerge -v --oneshot '>=emul-linux-x86-glibc-2.3.4.20041102'
></pre>
>
>2005.0 doesn't use symlinks from /lib32 and /usr/lib32 to the emul directories, so we need to change them into directories and copy over some important files.
>
><pre>
># rm /lib32 /usr/lib32
># mkdir /lib32 /usr/lib32
># cp /emul/linux/x86/lib32/libsandbox.so /lib32
># cp /emul/linux/x86/usr/lib32/libc.so /usr/lib32
># cp /emul/linux/x86/usr/lib32/libpthread.so /usr/lib32
># cp /emul/linux/x86/usr/lib32/*crt*.o /usr/lib32
># env-update
></pre>
>
>Now, we need to make sure our baselayout is up to date, so we can gurantee /etc/env.d/04multilib exists.
>
><pre>
># emerge -v --oneshot baselayout
></pre>
>
>We are now ready to actually switch the profile to 2005.0
>
><pre>
># rm /etc/make.profile
># ln -s /usr/portage/profiles/default-linux/amd64/2005.0 /etc/make.profile
></pre>
>
>Now just build glibc, unmerge the emul-* ones and update the base system.
>
><pre>
># emerge -v --oneshot '>=sys-libs/glibc-2.3.4.20041102'
># emerge unmerge emul-linux-x86-glibc
