I've spent the day on and off trying to get NS to work. It was really a matter of resolving the different dependancies, though one problem was a little obscure - I needed the X Server development package before I could install otcl.
Problems resolved, I can now check out the code I have for an assignment due in next week. More importantly, I have an easy way of grabbing screenshots - use VNC on Windows to connect to an X Session on this (Linux) server. That way I can have Linux on one monitor and Windows on another!
Here's my desktop - trop grand. Say hello to Zara on the right hand side there.
