Summary: I spent a good chunk of time installing eden on a fresh ubuntu vm from github, so I kept track of all of the packages that I needed to end up installing. users can install these before attempting to run the `build.sh` script in order to make sure all dependencies are there. Some of these manifested in non-obvious error messages. I'm sure as time goes on these dependencies might change a bit, but I think its a good starting point for anyone and should save a few hours of headache.
