Why are you trying to run refactor.py directly, rather than using 2to3
(http://svn.python.org/view/sandbox/trunk/2to3/2to3) as an entry

Agreed. A lot of the pending bugs seem to be related to the version of
lib2to3 in the stdlib, rather than the stand-alone product. Neal
Norwitz and I have been working to turn parts of 2to3 into a more
general refactoring library; once that's done (or even preferably
before), lib2to3 should be removed from the stdlib. It's causing far
more trouble than it's worth.
