When I tried to install via pip, I got the following error:

Installing collected packages: unipath
  Running setup.py install for unipath
      File "/usr/local/lib/python3.3/dist-packages/unipath/path.py", line 197
        fd = os.open(self, os.O_WRONLY | os.O_CREAT, 0666)
                                                        ^
    SyntaxError: invalid token

      File "/usr/local/lib/python3.3/dist-packages/unipath/test.py", line 48
        except Exception, e:
                        ^
    SyntaxError: invalid syntax

It means it is just 2 minor changes to make it Python 3 compatible.
