This is a brief explanation of how one might trouble shoot local emerge/ebuild failures. It is in no way comprehensive, and is only meant as an introduction to the topic:

Emerge errors during build_image

When following the Chromium OS Developer Guide emerge errors can be encountered for missing ebuild. A error that can be encountered when running build_image is:

emerge: there are no ebuilds to satisfy XYZ

Where XYZ is a library or other missing package.

This can be resolved by running:

emerge-$BOARD XYZ

Then recalling build_image:

./build_image --board=${BOARD} --noenable_rootfs_verification dev
