<p>What is this hidden package? You're writing your own package and you get:</p><pre><code> Could not find module `Data.Map': it is a member of package
containers-0.1.0.0, which is hidden.
</code></pre>

<p>You're building some other package and you get:</p><pre><code> Could not find module `Data.Map': it is a member of package

<div>besides, Howard, leksah is a small audience list,</div>
<div> </div>
<div>you may find more support on the cafe list, as your question as less leksah specific, but more on the "haskell bootstrapping procees"</div>
