Got a fresh Homebrew install of scala, giter8, sbt (0.11.3), and maven and everything checks out for the most part. brew doctor shows just known mods I've made by installing pcre and python 2.7 manually. When I get the play-scala template and then run it for the first time, I get the following unresolved deps on slf4j

```
# sudo sbt run
...

Running clean, reload, update manually:

```

What is the proper way to prevent this? Shouldn't these deps be downloaded during initialization?

Thanks!
