Config file issue / civicrm 4.6.8 / could not load the settings file
I think CiviCRM expects to find the CiviCRM module in /sites/all/modules/civicrm, as per: http://wiki.civicrm.org/confluence/display/CRMDOC/Installing+CiviCRM+for+Drupal+7

This affects the loading of the settings file, which is expected to be in a directory relative to this. We encounter the same issue and have a patch for it which we will submit back once it is a more generic fix.
