Cannot redeclare libraries_drush_command() After issuing the following command in the base drupal folder (/var/www/html) 

$ drush status


I get the following response. 

PHP Fatal error:  Cannot redeclare libraries_drush_command() (previously declared in /var/www/html/profiles/commons/modules/contrib/libraries/libraries.drush.inc:13) in /var/www/html/sites/all/modules/libraries/libraries.drush.inc on line 25

This is a new server install using RHEL 6.4 (Santiago) and drush 6.0 installed through pear. 

Where I might begin to fix this?
Removing /var/www/html/sites/all/modules/libraries/libraries.drush.inc cleared things up. I bungled things up somewhere. IRC #drupal-commons confirmed Clive's note above.
