Tesseract 3.02 not return list of Language and pdfocr.rb stop execution with error.

[unclehook]

--list-langs is not more a parameter of tesseract and return the usage message.
To execute ocrpdf.rb I had to comment out the following lines.

From line 253 to 276:

if checklang
  langlist = []
  if usecuneiform
    begin
      langlist = `cuneiform -l`.split("\n")[-1].split(":")[-1].delete(".").split(" ")
    rescue
      puts "Unable to list supported languages from cuneiform"
    end
  end
  if usetesseract
    begin
      langlist = `tesseract --list-langs 2>&1`.split("\n")[1..-1]
    rescue
      puts "Unable to list supported languages from tesseract"
    end
  end
  if langlist and not langlist.empty?()
    if not langlist.include?(language)
      puts "Language #{language} is not supported or not installed. Please choose from"
      puts langlist.join(' ')
      exit
    end
  end
end
