title: Julia error: no method haskey(Dict{String,Dict{String,String}},ASCIIString)
body: <p>I'm trying to test out the Winston plotting engine in Julia. I installed the package but I'm getting some errors now when I try to compile one of the examples:</p>
  
  <pre><code>&gt; julia example1.jl
  Warning: could not import Base.haskey into Inifile
  Warning: could not import Graphics.set_source into Color

  <p>can anyone tell me what's going on? It seems to be that it can't find <code>Base.haskey</code>, but I'm not sure how to address that.</p>
