I have been trying to add cando to my schooltool installation and it's been coming up with all sorts of errors during the make proces; it just stops at one of the packages and never report anything until i interrupt the installation and it would give this traceback error; the error given varies each time it is interrupted;

I had previously installed cando on another system without any of these issues using the same process, so what could be wrong?
