title: How do I install a LaTeX .sty file on OSX?
body: <p>I have a LaTeX project set up:</p>
  
  <pre><code>tex/
    - documents/
        - some_file.tex
    - support/
        - todonotes.sty
  </code></pre>
  
  <p>where <code>some_file.tex</code> uses <code>todonotes</code>:</p>
  
  <pre><code>\usepackage[colorinlistoftodos,textwidth=0.9\marginparwidth]{todonotes}
  </code></pre>
  
  <p>But I get "LaTeX Error: File `todonotes.sty' not found" when I try to build the PDF in TextMate. How do I tell LaTex or TextMate about my .sty file?</p>
  
  <p><strong>Later</strong></p>
  
  <p>To be specific, I'm using <code>tetex</code> from MacPorts, though given the answers so far, I might try another distribution.</p>
