You are trying the doctest binary from the command line and not the library interface? I tried this with ghc 7.0.3 and doctest 0.4.1 but could not reproduce it with "$ doctest Fib.hs". On the other hand you have in the example a space before "-- | Compute.." and that produces a parse error for me.

This is the content of Fib.hs:

module Fib where  -- | Compute Fibonacci numbers --
