Ah, this is because the app uses go-sqlite3, which you haven't gotten in your local repo yet. I need to fix the command line to download all dependencies first.

You can fix it manually with:

    go get github.com/mattn/go-sqlite3

Also, I believe that the go command line figures out the dependencies for you, so this should get everything you need:

    go get github.com/robfig/revel/samples/booking
