[wxPython] NameError: name 'wxColour' is not defined

Hi,

I'm trying to install wxPython 2.3.1 on Solaris 2.7.
First I installed wxGTK 2.3.1 with no problems.
The installation of wxPython was also no problem BUT when
I import the module I get the following exception:

Python 2.1 (#1, Jun 24 2001, 20:43:31)
[GCC egcs-2.91.66 19990314 (egcs-1.1.2 release)] on sunos5
Type "copyright", "credits" or "license" for more information.

import wxPython.wx

Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/opt/python/2.1/lib/python2.1/site-packages/wxPython/wx.py", line 1501, in ?
    wxColor = wxColour
NameError: name 'wxColour' is not defined

Thanks in advance,
  -Thorsten
