I am interested in compiling KDE SC on a stock ubuntu-server distribution in under 7 days, and then updating the documentation so that a new contributor to KDE can do this in under 6 days. I think the huge up-front commitment to build from trunk is a barrier to entry for new contributors.
Here is a list of documentation that I am consulting and working on. They are listed in order from http://kde.org/community/getinvolved/, a place where new contributors can start, and is hierarchal based on hyper links. Action that is required is also included on this list. Ultimately, this should result in a runnable system.
