  31 <div class="paragraph"><p>You can compile MLton with <a href="SMLNJ">SML/NJ</a>, however the resulting
  32 compiler will run much more slowly than MLton compiled by itself.  We
  33 don&#8217;t recommend using SML/NJ as a means of
  34 <a href="PortingMLton">porting MLton</a> to a new platform or bootstrapping on a
  35 new platform.</p></div>
  36 <div class="paragraph"><p>If you do want to build MLton with SML/NJ, it is best to have a binary
  37 MLton package installed.  If you don&#8217;t, here are some issues you may
  38 encounter when you run <span class="monospaced">make smlnj-mlton</span>.</p></div>

  58 distributed with a binary package of MLton.  The easiest solution is
  59 to copy the front-end lexer/parser files from a different machine
