jasminerice_reporter not found?

[svanschooten]

In my rails application the command

rake jasminerice:run

does not run since it cannot find the jasminerice_reporter, which should be included in the gem....It also says that it cannot find my spec.js, but I'm testing coffeescript, so it's called spec.js.coffee (according to definition in the jasminerice documentation). This all is very confusing since I'm trying to integrate the coffeescript testing into my jenkins ci, and nothing has worked out for me so far.
This is my output:

$ rake jasminerice:run
Running jasmine specs
jasmineRiceReporter not defined! Check your configuration to make
sure that spec.js exists and that jasminerice_reporter is included.
rake aborted!
