gem "configatron", "~> 2.8.2"
Settings = Configatron.instance
Settings.foo = "foo"
puts Settings.foo # ok
Settings.import = "import"
puts Settings.import # nothing to print

I think the solution would be to define your configatron settings outside of the Rakefile, and bring them in via require or something.
The problem is that you're defining something in the Rakefile "space".
