I am installing Gentoo on my laptop and I want to migrate to GCC 3.4, but find myself wondering when exactly is the right time to do this, should I follow the entire installation documentation, and only *then* follow the migration guide at http://www.gentoo.org/doc/en/gcc-upgrading.xml#first-install, or can I do this for example when still booted form the Gentoo CD, while chrooted, before even building a custom kernel? I suppose the earlier the 'better' (i.e. less time wasted recompiling stuff) but maybe there are some problems with doing it this way. Whatever the answer is, perhaps this should be added to http://www.gentoo.org/doc/en/gcc-upgrading.xml#first-install (or maybe even mentioned somewhere in the install docs, if appropriate).
(In reply to comment #0) Seeing as the 2006.0 media incorporates the most recent stable toolchains for each arch, you shouldn't *need* to upgrade GCC. If you use something really old like a 2005.0 CD, then you would want to upgrade ASAP. The idea is that you upgrade gcc and rebuild your world (emerge -e system && emerge -e system && emerge -e world && emerge -e world, more or less) *before* you have tons of packages on there. That way you keep the recompiling to a minumum. Afterwards you can go ahead and start installing Gnome, OOo, etc. and they will be built with your new toolchain. Or just use the latest installation media available for your architecture and you shouldn't have a problem (right now, anyway ;))

Ideally, this should have gone to #gentoo on irc.freenode.net or http://forums.gentoo.org since this isn't a "Bug" per se. That said, the upgrade guide specifically states "A GCC upgrade on a system after installation from a stage3 tarball is a simple affair." and IMHO nothing can really be clearer than that.
