title: Doxygen and Graphviz on Lion
body: <p>I have succesfully installed Doxygen and GraphViz on my mac (running Lion OS), but when I run doxygen with graphViz I get following error messages:</p>
  
  <pre><code>1) sh: dot: command not found
  2) Problems running dot: exit code=127, command='dot', arguments='"/Users/../xxx.dot" -Tpdf -o
  3) error: problems opening map file /Users/.../xxx_graph.map for inclusion in the docs!
  If you installed Graphviz/dot after a previous failing run, 
  try deleting the output directory and rerun doxygen.
  </code></pre>
  
  <p>It must be a problem with my Graphviz/dot paths, but I dont know how to solve it.</p>
  
  <p>I have already installed Graphviz using MacPorts but I still get the same error messages.</p>
  
  <p>What could I do to solve this problem? Thanks in advance!</p>
