Redmine

I am looking for a bit of direction

I took an ubuntu 10.10 VM, followed the install instructions at http://www.redmine.org/projects/redmine/wiki/HowTo_Install_Redmine_in_Ubuntu. At this point, I went to the site and it was working. I backed up the database, loaded a copy of our current .7.3 install, then followed the upgrade instructions at http://www.redmine.org/projects/redmine/wiki/RedmineUpgrade. The problem is when I try to update the Database, and I get:

** Execute db:migrate
==  PopulateMemberRoles: migrating ============================================
rake aborted!
An error has occurred, all later migrations canceled:

I am at a loss, and google isn't much help. The info page from our current install:
