Hi all, After a fair bit of tutorial related pain on the mailist recently, I've just forked the tutorial-devel repo to https://github.com/jack-h/tutorials_devel and recompiled tutorials 1-3 with Sysgen 11.5 and the libraries in the main casper github repo.
The tutorials in the 2011 directory *should* work (along with their python counterparts). Feel free to give those a go and give me a shout if you still have problems.
