title: Gruel required to compile myblock
body: <p>So I was following the gnuradio tutorial on building an OOT. However i got into trouble with boost so i followed a solution that made me install boost and export by the command: </p>
  
  <pre><code>export LD_LIBRARY_PATH=$BOOST_PREFIX/lib
  </code></pre>
  
  <p>I did that and got into another error after running cmake (below)</p>
  
  <pre><code>$cmake ../
