I believe this comes up in the assignment of class variables in the Check class in checker.py. SET is not there, at least as of 0.4, and this may be related to the fact that PyFlakes does not support the AST for Python 2.7, as seen in constructs like dict comprehensions (with the DICTCOMP attribute), which raised the same AttributeError.
You can reproduce this error readily by running pyflakes on Ensemble source on trunk r321.
