OT for the original question, but there is a way to lessen the amount of work done if a package may need to be merged (or attempted to be merged) repeatedly. You have to do it manually though: - ensure all needed deps are already installed - ebuild <package> <command> where <command> is on of fetch, unpack, compile, install, etc as detailed in the ebuild man page. You can't restart a failed compile from where it left off [you can do that if you are running make manually, but ebuild abstracts that away] but at least some work can be omitted. If course, this in no way answers the original question, but it's occasionally useful to know -- alan dot mckinnon at gmail dot com
