The Workout source code is now available for you to checkout and build from the KDE subversion repository. Like all new projects it has for now been imported into KDE's playground. It will soon move to KDE review and then, if the review goes well, to KDE extragear.
Until then, get it from here:
$ svn co svn://anonsvn.kde.org/home/kde/trunk/playground/edu/workout
Do not forget to set HAVE_KDE to 1 in your cmake command line when building the KDE version.
