Why does the Albacore zip task fail on IronRuby?

Question

I am trying to zip with the zip task in Albacore, but I get an error. Is it a problem with IronRuby?

task :publish => :build do
  Rake::Task[:service].invoke
  Rake::Task[:site].invoke
  Rake::Task[:zip_svc].invoke
end

zip :zip_svc do |zip|
  zip.directories_to_zip 'publish'
  zip.output_file = 'Svc.zip'
  zip.output_path = File.dirname(__FILE__)
end

Error>

** Invoke zip_svc (first_time)
** Execute zip_svc
rake aborted!
wrong number of arguments (1 for 2)

Unfortunately, the zip task is one of the few items that does not work correctly in IronRuby. I've looked several times, but have not found a suitable replacement for the rubyzip lib, either. I recommend using an external tool like 7-zip (free/very good tool) and call it from the exec task.
