title: Trouble with tutorial on getting started with Webassembly
body: <p>I'm following the guide <a href="http://webassembly.org/getting-started/developers-guide/" rel="nofollow noreferrer">here</a> for creating a Hello World wasm application (Mac OS). I followed everything to a T, and am sure <code>git</code> and <code>python</code> are in my <code>PATH</code>, and 90% sure <code>cmake</code> is in my path. The installations were long but went fine. When I type the command <code>emcc hello.c -s WASM=1 -o hello.html</code> into my terminal, however, I receive the message <code>-bash: emcc: command not found</code>. Tried to <code>sudo</code> it too. </p>
  
  <p>Not sure what the issue is. I'm obviously extremely green to wasm. Thanks!</p>
