Can't have a drupal-org.make file to make a full Drupal distribution until Drupal 8 and Blog module have full releases:
core = 8.0api = 2projects[blog][subdir] = contribprojects[blog][version] = 2.0
Updated issue summary.
We're actively working on lifting this restriction. See http://drupal.org/community-initiatives/drupalorg/distribution-packaging... for more.
