Fatal error: Cannot redeclare autoadmin_get_page_description() (previously declared in .../htdocs/sites/all/modules/contrib/autoadmin/autoadmin.helper.inc:21) in .../htdocs/sites/all/modules/contrib/autoadmin/autoadmin.helper.inc on line 39

I temporary fixed it by changing all 'require' statements in autoadmin.drush.inc to 'require_once'.

sed -i "s/^require /require_once /g" /path/to/autoadmin/drush/autoadmin.drush.inc
