widget_users modification

I have the widget-users running on newly created blogs.
The widget runs fine except that it shows sitewide users.

However, I would like to be able to show ONLY users from the associated blog.

(i.e blog1 users shown on blog1, blog2 users shown on blog2, etc)

What change would I have to make to the following code to make this happen?

// $query = "SELECT ID, display_name FROM " . $wpdb->base_prefix . "users WHERE spam != '1' ORDER BY user_registered DESC LIMIT " . $options['users-number']; //
