I had no problem getting past the opcode problem with the new version of minilogin installed:
Minilogin 0.6.1
I don't know if that is what is making it work but just thought I would comment incase it helped anyone.
My problem is I get all the way past that and then the Boot5zones batch takes a crap on me :P It is the 6.1 DR1 version. Any advise on that part?
