module datetime introuvable

Voilà, c'est mon premier programme en Python. Il provient de la revue 'Linux Journal', juillet 2005, p.20. Lorsque je fais rouler le programme, le message suivant s'affiche: 'no module named datetime'. Je travaille en Linux RedHat 8.0. Le package mx-2.0.3-6.rpm était déjà installé. J'ai désinstallé le tout, réinstallé le package egenix-mx-base-2.0.6-py2.2_1.i386.rpm et l'erreur persiste toujours. Où est l'erreur? Voici le programme: #!/usr/bin/python # Grab the CGI module import cgi import psycopg import icalendar from iCalendar import Calendar, Event from mx.DateTime import datetime from iCalendar import UTC # timezone # Log any problems that we might have import cgitb cgitb.enable(display=0, logdir="/tmp") # Send a content-type header print "Content-type: text/calendar\n\n" # Create a calendar object cal = Calendar() # What product created the calendar? cal.add('prodid','-//Python iCalendar 0.9.3//mxm.dk//') # Version 2.0 correspond to RFC 2445 cal.add('version', '2.0') # Create the database connection db_connection = psycopg.connect('dbname=calendar user=postgres') db_cursor = db_connection.cursor() db_cursor.execute ('''SELECT event_id, event_summary, event_location, event_start, event_end, event_timestamp FROM Events ORDER BY event_start''') result_rows = db_cursor.fetchall() for row in result_rows: # Create one event event = Event() # Set the event ID event['uid'] = str(row[0]) + 'id@ATF' # Set the description and location event.add('summary', row[1]) event.add('location', row[2]) # Transform the dates appropriately event.add('dtstart', datetime(tzinfo=UTC(), *row[3].tuple()[0:5])) event.add('dtend', datetime(tzinfo=UTC(), *row[4].tuple()[0:5])) event.add('dtstamp', datetime(tzinfo=UTC(), *row[5].tuple()[0:5])) # Give this very high priority! event.add('priority', 5) # Add the event to the calendar cal.add_component(event) # Ask the calendar to render itself as an iCalendar # file, and return that file in an HTTP response print cal.as_string() Si quelqu'un peut m'aider, ce sera apprécié! Merci

au lieu de  
      from mx.DateTime import datetime
tu devrai essayer
     from mx.DateTime import wxdatetime
