[SOLVED] TestFirst Teaching Pig Latin 'rspec

I'm in the course of completing the Pig Latin exercise from TestFirst Teaching, but after I made the Ruby file and attempted to run rake, I got the following error:

(See full trace by running task with --trace)

I think it may have something to do with the version I'm running, but I'm not at all sure.

Mac OSX 10.8.2
Ruby 1.8.7
Rspec 2.13.1
Rake 10.0.4

NOTE! When I run rake on the previous exercises (0-3) they work just fine, but nothing after that works...

EDIT: I updated my rake version, and now when I try to run rake I still get a 'rspec_config failed' error, but I get this as well. HELP!!!

EDIT #2: Here's the source code for my Pig Latin exercise, since it says it's a syntax thing.

def isvowel?(letter)
  vowels = ["a", "e", "i", "o", "u"]
  vowels.include?(letter)
end

def translate(word)
  i = 0
  cons = []

  while !isvowel?(word[i])
    cons << word[i]
    i+=1
  end

  word[i..-1] + cons.join()[0…i] + "ay"
end

def translates(string)
  if !string.include?(" ")
    translate(string)
  else
    new = string.split(" ").collect { |word| translate(word) }
  end

  new.join(" ")
end
