Hi PortDude, good to see you're making a new site with our beloved CMS
You should create the block position manually, taking care to use the correct naming so the theme and the system know that they are talking about the same thing.
Currently, there is no installation procedure for themes, so the themes cannot create the elements (blocks, block positions, ...) they need for their specific use. It's something that will come in the future, though I can't point a release on that yet.
