PyGUI installation issue

[Wallflower]

I get is this error:

$ python blobedit.py
Traceback (most recent call last):
File "blobedit.py", line 1, in <module>
from GUI import Window, Label, Font, application
File "/usr/local/lib/python2.7/site-packages/GUI/Window.py", line 12, in <module>
from GUI.Utils import NSMultiClass, PyGUI_NS_EventHandler, PyGUI_Flipped_NSView
File "/usr/local/lib/python2.7/site-packages/GUI/Utils.py", line 71, in <module>
class PyGUI_NSActionTarget(NSObject):
objc.BadPrototypeError: Objective-C expects 1 arguments, Python argument has 3 arguments for <unbound selector call_method of PyGUI_NSActionTarget at 0x10933a578>

Any help, ideas?

Suggestion: Remove python2.7 from your computer and install a modern Python.
