I edited your code and just changed a couple lines: http://pastie.org/807473

I changed this:
input_file_stream = File.open(input_filename, "r")

To this:
input_file_stream = IO.readlines(input_filename)

Using IO.readlines will just read the entire contents of the file and store
each line as an element in an array.  You can then iterate through the array
rather than using a while loop.

I changed your loop and changed the line where you split the lines of the
csv file from this:
  input_file_line = input_file_stream.gets.to_s.split(/,/)

To this:
  input_file_line = line.split(/,/)

This should work, I obviously did not test it.  Hopefully this will point
you in the right direction.

Bryan
