SimpleTwitter needs the php cURL library to be installed
SimpleTwitter uses the cURL php library to connect to the Twitter website.
This doesn't seem to be available with your current php configuration - it has
possibly been disabled in your php.ini file.
Please contact your
System Administrator or Service Provider for information.
