I have to say that I stumbled upon the same error message, until the moment when I launched directly (from Poser's menu > Run PYthon script, directely in the material room)

runtime : Python : poserScripts : structure : nodeTidier : _noteTidier_3.pyc

I suppose that the error message comes probably from a problem with the way it's installed or configured. When I launch directly the named compiled script, it works.
