Emerge order is not deterministic, especially with parallel builds. The reason is that it does not need to be according to the dep graph - if two packages are at the same level and do not depend on each other, then the order they are built in does not affect the final result. Practically all parallel processing works this way. What is deterministic, is that if you build the same set of packages twice and even if portage does them in different order, the binaries produced are functionally identical -- Alan McKinnon alan.mckin...@gmail.com
