They haven't opened the SVN server, the last time I checked. Also, as a note, the code that is on the SVN server right now is the source code for all the WPI Library code (eg. RobotDriver.cpp, Gyro.cpp, etc.) The header files are installed when you install WindRiver Workbench.
On the first site there is a like to the current update (build 1562) is located here:
http://first.wpi.edu/FRC/frcupdates.html
The larger file is the actual update, the smaller file is the source code for the WPI Library.
As if last week the 1562 build that is available above is either the same or more current the the SVN build on the beta WPI SourceForge site.
Note: Make sure you accomplish the benchtop test PRIOR to applying any of the updates. The instructions are tailored to the unmodified installed.
