A user of mine wanted to use ghost as their top level site. After figuring out that node.js was missing we tried to install that, but no combination of things work.
Since it would seem that node.js should almost be a global setting, it's not very clear how to install both of these apps to get them to function.
Also, we were surprised that, since it's on your install menu, that it didn't "just work"
So how to we get ghost to run in a domain hosted on my server?
