context_get_plugin() is called but no context module in the distro

As a site builder, after enabling another module, I receive this error on all site pages but not on admin pages:

Fatal error: Call to undefined function context_get_plugin() in /Users/joe/Sites/mohair/htdocs/profiles/openenterprise/modules/defaultcontent/defaultcontent.module on line 496

Here's the offending code. It is calling a context module func, but there is no context module in the OE distro.

<?php
/*
 * Implements hook_node_view().
 */
function defaultcontent_node_view($node, $view_mode, $langcode) {
  if ($plugin = context_get_plugin('condition', 'defaultcontent')) {  // <-- line 496
    $plugin->execute($node);
  } 
}
?>

A screenshot of the callstack is attached.
