PHP Fatal error: Call to undefined function webform_menu_to_arg()

Hello,

I got the latest pressa release which has security update of drupal 7.38. I created an empty database in mysql and ran the DB scripts that came with the pressa release to populate the database. I unzip the full install under the sites folder and update the settings.php with the db information but when I go to the site in browser, it displays nothing. In the htttpd log, I see the error

[Tue Aug 11 21:19:16 2015] [error] [<client IP>] PHP Fatal error:  Call to undefined function webform_menu_to_arg() in /var/www/html/includes/menu.inc on line 816

The php running on my machine is :-
