[vtkusers] OSX on intel universal build import error for _glcanvas.so

[Dan White]

Dear wxPython and VTK developers

while running our BioImageXD python application from the command line
on my MacBookPro OSX 10.4 with universal build installs of python2.4  
and wxPython2.6-mac-unicode
I get an interesting error that looks like a problem with xwPython,

I can replicate the error with the following:

daniel-whites-computer:~ bioimagexd$ /usr/local/bin/python2.4
Python 2.4.3 (#1, Apr  7 2006, 10:54:33)
[GCC 4.0.1 (Apple Computer, Inc. build 5250)] on darwin

 >>> import wx

     import wx.glcanvas

Is this a problem in xwPython?	

I haven't noticed the same problem on a PowerMac PPC G5 with PPC  
python 2.4 and wxPython2.5.5-mac-unicode

cheers
