The AWS SDK for PHP Module comes with a drush make script:
; Drush Make (http://drupal.org/project/drush)
api = 2
core = 7.x
projects[awssdk][type] = library
projects[awssdk][download][type] = git
projects[awssdk][download][url] = https://github.com/amazonwebservices/aws-sdk-for-php.git
projects[awssdk][download][tag] = 1.5.10
projects[libraries] = 2
What do I need to do to get this SDK manually? I am running Windows and I ran into some issues trying to add the script using drush. I already tried adding the sdk folder to /sites/all/libraries as "awssdk" but that did not work as I keep getting "Failed to load the AWSSDK" in Drupal reporting.
