rules_scheduler.drush.inc causing Drush to crash

When I try to run cron from a terminal window using the 'drush cron' command, I get the following error message:

Drush command terminated abnormally due to an unrecoverable error.                                                       [error]
Error: Cannot redeclare rules_scheduler_drush_command() (previously declared in
/home6/norther1/public_html/profiles/openoutreach/modules/contrib/rules/rules_scheduler/rules_scheduler.drush.inc:12) in
/home6/norther1/public_html/sites/all/modules/rules/rules_scheduler/rules_scheduler.drush.inc, line 29

At first I thought is was a problem with Elysia Cron, but have removed that modules and the problem persists.

I am including a screen shot since the message ran off the screen.

Thanks in advance for looking into this!
