Hello:

I'm using your current (last commit) makefile in a stub makefile an I've got the following errors (all the other downloads went fine).

acquia_connector downloaded from http://ftp.drupal.org/files/projects/acquia_connector-6.x-1.10.tar.gz. [ok]
Could not retrieve package information for /tmp/drush_make_tmp_1300726484/acquia-search-current.tar.gz. [error]
