body: <p>I was following <a href="http://andarazoroflove.org/how-to-create-alt-coin-scrypt-clones-for-fun-and-profit-bitcoin-litecoin-secrets-exposed/" rel="nofollow">this</a> guide:</p>
  
  <p>When I ran:</p>
  
  <p><code>make -f makefile.osx USE_UPNP=-</code></p>
  
  <p>here is what I got in the terminal: </p>
  
  <pre><code>/bin/sh ../share/genbuild.sh obj/build.h
