  19. 				<p>The Python Package Manager helps you installing additional
    20. 

  20. 				packages that enhance Python. It determines the exact MacOS version
    21. 

  21. 				and Python version you have and uses that information to download
    22. 

  22. 				a database that has packages that are test and tried on that
    23. 

  23. 				combination. In other words: if something is in your Package Manager
    24. 

  24. 				window but does not work you are free to blame the database maintainer.</p>
    25. 

  25. 				
    26. 

  26. 				<p>PackageManager then checks which of the packages you have installed
    27. 

  27. 				and which ones not. This should also work when you have installed packages
    28. 

  28. 				outside of PackageManager.
    29. 

  29. 				You can select packages and install them, and PackageManager will work 
    30. 

  30. 				out the requirements and install these too.</p>
    31. 

  31. 				
    32. 

  32. 				<p>Often PackageManager will list a package in two flavors: binary
    33. 

  33. 				and source. Binary should always work, source will only work if
    34. 

  34. 				you have installed the Apple Developer Tools. PackageManager will warn
    35. 

  35. 				you about this, and also about other external dependencies.</p>
    36. 

  36. 				
    37. 

  37. 				<p>PackageManager is available as a separate application and also
    38. 

  38. 				as a function of the IDE, through the <tt>File-&gt;Package Manager</tt> menu
    39. 

  39. 				entry. </p>
    40. 

  40. 				
    41. 

  41. 				<h2>Troubleshooting</h2>
    42. 

  42. 				
    43. 

  43. 				<p>If package manager fails to open the database first check that you are
    44. 

  44. 				connected to the internet. If you are connected then the problem
    45. 

  45. 				could be that there is no database (yet?) for your version of Mac OS X.
    46. 

  46. 				You may be able to find an alternative
    47. 

  47. 				database that works for your system at
    48. 

  48. 				<a href="http://www.python.org/packman">http://www.python.org/packman</a>.
    49. 

  49. 				In the standalone Package Manager you can then open such an alternative database
    50. 

  50. 				with the <tt>File-&gt;Open URL...</tt> command, but you should realize that
    51. 

  51. 				you are now on untested ground.</p>
    52. 

  52. 				
    53. 

  53. 				<p>Another potential problem source is that you are behind a firewall. This version
    54. 

  54. 				of PackageManager uses the Unix method of setting a firewall: you need to set the
    55. 

  55. 				environment variable <tt>http_proxy</tt> to <tt>"http://<i>proxyhost</i>:<i>port</i>"</tt>.
    56. 

  56. 				See <a href="http://developer.apple.com/qa/qa2001/qa1067.html">Apple Technical
    57. 

  57. 				Q&amp;A QA1067</a> for instructions.</p>
