The scripts to allow parallel package building. See the README file in Tools/portbuild for details. Note that this is still a major work in progress. I probably forgot something but I need to go to sleep. At least it works here (most of the time :).

(1) Do not delete and recreate the chroot dir for every new package that is built. This saves a lot of time, especiall when the parallelism (the number of jobs per machine, not the number of machines) is low. However, the build script only blows away /usr/local and /usr/X11R6, so if there is a port that does some nasty things outside that area, all bets are off. (2) Better load balancing. Now, each machine reports its own load in a form of a text file, which the master merely aggregates to pick the lowest-loaded machine(s). Other than generally running faster (and more up-to-date) under loaded conditions, the master script will no longer hold up until a timeout when a machine goes down.
