Warning on test run: slacker.rb:53: warning: Using the last argument as keyword parameters is deprecated

[ssg47]

I've just done an offline installation of slacker on Windows (file versions below) and followed the instructions to run a test project:

slacker_new my_project

Edited ./my_project/database.yml to provide server/database settings and run slacker:

I found this but, frankly, Ruby isn't my thing (yet) and I don't really understand it).
