The version you mentioned is in CURRENT (8.0) and proberly is not
compatible with RELENG_7 at the moment.
There have been a lot of changes to the scheduling and other stuff
commited by jeff, read jeff's  techjournal!
I recall also in the mailing list that not all of those changes are
being commited to RELENG_7
