play scala "does not seem to host a valid application"

[Thomas Wiradikusuma]

Hi guys, I'm just starting to learn Play with scala, but I can't make
it work. Here's the screen (I paste all, in case it's important):

septerra:~ wiradikusuma$ play install scala-0.9

What did I miss?

You may either call `play run path/to/your/app` or just `play run` if
your current directory is your application root directory. You were in
the latter case after running the `cd myScalaApp/` (so write `play
run` instead of `play run myScalaApp/` to run your application).

Thanks, didn't notice that. I'll try it once I reach home.
