That's because Ruby 1.8.7 has a different CSV library.  You'll need to use FasterCSV there to get the same interface.  Change your require to something like:

if RUBY_VERSION < "1.9"
  require "rubygems"
  require "faster_csv"
  CSV = FCSV
else
  require "csv"
end

This is a non-CSV related complaint about your code.  On line 35 of the gerar.rb file you have used a non-ASCII character.  To do this in Ruby 1.9, you must specify the encoding of your file.  If it's UTF-8, making this the first line of the file should fix it:

  # encoding:  UTF-8

Hope that helps.
