[Boa Constr] boa crashes

[D. R. A. <ru...@co...>]

Hi there. I'm trying to find an IDE to build GUI Python apps with and 
BOA looked like it was the right one to use, but I can't get it to run. 
I'm using:

RedHat 8.0
python 2.2.1-17
wxPythonGTK-py2.2-2.3.3.1-1

and when I run Boa.py I get:

Starting Boa Constructor v0.1.0-alpha
importing wxPython
setting user preferences
running main...
Traceback (most recent call last):
  File "Boa.py", line 495, in ?
    main()
  File "Boa.py", line 475, in main
    app = BoaApp()
  File "Boa.py", line 310, in __init__
    wxApp.__init__(self, false)

  File "Boa.py", line 321, in OnInit
    abt = About.createSplash(None, modTot, fileTot)
  File "About.py", line 132, in createSplash
    return AboutBoxSplash(parent, modTot, fileTot)
  File "About.py", line 151, in __init__
    self.html = Utils.wxUrlClickHtmlWindow(self.blackback, -1, 
flags=wxCLIP_CHILDREN)
  File "/usr/lib/python2.2/site-packages/wxPython/html.py", line 609, in 
__init__
    self.this = apply(htmlc.new_wxHtmlWindow,_args,_kwargs)
TypeError: 'flags' is an invalid keyword argument for this function
Exception exceptions.TypeError: "'NoneType' object is not callable" in

help?

TIA
