From Gentoo Wiki
If you've got another faster computer, you can set up distcc to compile binaries for your slower PPC processor. It is better to do as much building as possible on the faster machine; if possible, do not build on the slower computer. Read the DistCC Cross-compiling article to learn how. You may also want to read the Gentoo Embedded Handbook to learn more about cross-compiling.
