-Also, do not worry about the cross-compiler interfering with your native build -system. All of the toolchain packages are designed such that they are isolated -from each other based on the target. This way you can install cross-compilers -for whatever architecture you wish without breaking the rest of your system. +You do not have to worry about the cross-compiler interfering with your +native build system.

To keep +your Gentoo installation clean, we highly recommend that crossdev +installation and all cross-compiling activities occur inside a Gentoo +stage3 chroot. (This is the same chroot you used to install Gentoo.)
