Rake migrate fails on passing a string to ActiveRecord::Base.establish_connection

[ilit-all]

When installing according to INSTALLATION.md via Ubuntu 14.04, I get the following error. Does anyone have any idea what causes this?

Looks like you haven't setup database.yml correctly, but it's certainly not a bug in our code.

If you need help please use IRC or the mailing list.

Incidentally nothing in the instructions tells you to use sudo when migrating the database and I wouldn't recommend it.

Thank you very much, Tom!
