Andy Oliver: I suspect is the configuration that Sammy boy uses to run Gump on his Thinkpad… It is building all of Jakarta/XML/etc., so its understandibly a lot for my T-30 to do. Somehow, I manage on my T-23. Also, I think you underestimate the community. Centipede is getting on board – by starting small. My guess is that the JAXP stuff can all be removed. FYI: here is a complete list of dependencies that are required for a full build.
