Can't seem to figure how to compile

[John Vogel]

Running ghc 6.6.1
On Windows Vista

I get this error when I run: ghc Main.hs

gcc: installation problem, cannot exec `as': No such file or directory

On this code:

module Main where

main = do
  putStrLn "Please enter your name: "
  name <- getLine
  putStrLn ("Hello, " ++ name ++ ", how are you?")


What is my problem?
