wx opengl error

hi

i am testing a wxpython opengl application under ubuntu linux and i get this error:

Traceback (most recent call last):
   File "wxOpenGL3_1.py", line 172, in ?
     a = FrameApp(0)
   File "/usr/lib/python2.3/site-packages/wxPython/wx.py", line 1951, in
__init__ _wxStart(self.OnInit)
   File "wxOpenGL3_1.py", line 156, in OnInit
     canvas = Canvas(frame, -1, position, size, fps, bgcolor, trails)
   File "wxOpenGL3_1.py", line 100, in __init__
     MyCanvasBase.__init__(self, parent, id, pos, size)
   File "wxOpenGL3_1.py", line 31, in __init__
     self.Bind(wx.EVT_ERASE_BACKGROUND, self.OnEraseBackground)
AttributeError: Canvas instance has no attribute 'Bind'

I never got this error before while i was developing the app under OSX and i dont really understand why this is happening.

thanks
