title: Python error on building Dart on Windows
body: <p>I'm trying to build Dart on Windows XP (according to the docs) but while using Python to do it, it encounters an error in the script file:</p>
  
  <pre><code>D:\Documents and settings\xxx\Mes documents\Google_Dart\dart&gt;python tools/bui
  ld.py --arch=ia32
  File "tools/build.py", line 51
  print "Unknown mode %s" % mode
                        ^
  
  SyntaxError: invalid syntax
  </code></pre>
  
  <p>Any hint on how to solve this? Can the problem be that my version of Python is too recent? (3.2.2)</p>
