I'm getting this error when trying to sort the migration list for the phpbb forum I'm trying to pull. I get a bunch of

No migration found with machine name phpbb__*

Then failure to sort list possibly due to circular dependencies. I've tried both migrate 2.5 anf 2.6 as well as phpbb2drupal 3.x-dev and 4.x-dev and have gotten the same errors on both. I could use some help on this.
