[MacRuby-devel] DictionaryServices

[ecin]

I'd like to use Dictionary Services (http://developer.apple.com/mac/library/documentation/UserExperience/Reference/DictionaryServicesRef) to look up definitions in a MacRuby app, but am having a hard time figuring out exactly what I need to require in order to access its functions, as

framework 'Cocoa'
framework 'CoreServices'

doesn't do the trick. Is this another example of missing bridge support, or am I missing something else?
