Invalid Syntax in Scanner.py

[mscdex]

While attempting to do python setup.py install I get this error (Python 2.6.5):

SyntaxError: ('invalid syntax', ('/home/mscdex/bin/lib/python2.6/site-packages/uncompyle/Scanner.py', 762, 60, '                        num_pj += len({ self.lines[a][0] for a in self.__all_instr(code, k, prev_end, (POP_JUMP_IF_FALSE, POP_JUMP_IF_TRUE), target)})\n'))
