wxPython import error...

[king kikapu]

Hi,

i am just completed installing Python/Pydev/Eclipse/wxPython on an
Ubuntu system and all are running fine except program that contains
references to wx

It gives me:
ImportError: /usr/lib/python2.4/site-packages/wx-2.8-gtk2-unicode/wx/
_core_.so: undefined symbol: PyUnicodeUCS4_FromEncodedObject

I installed the wx packages the way the wx web site says, especially
for Ubuntu.

Can anyone help with this as i have been searching the net for this
with no luck...

Thanks for any help
