[Pythonmac-SIG] Universal wxPython app fails when run on second (PPC) machine

[Erik Westra]

Hello again,

Sorry for taking so long to reply -- I've been swamped with other  
work lately.

I had a report today from one of the people in my development team  
who also has a MacBook, and had exactly the same error message on his  
Intel-based machine:

So I don't think this is a universal binary problem, but rather a  
more general problem with standalone wxPython apps built using  
py2app, regardless of whether they are run on an Intel machine or a  
PPC machine.

Doodle works fine, on both Intel and PPC.  But when I tried building  
demo/PyCrust.py into a standalone application and running it on a  
separate machine, the above error message reappeared.  So it's not  
just my particular application that's failing -- it seems to be a  
more general problem with any wxPython application that makes use of  
wx.stc.

Any suggestions for how I can fix this?  I'm going to try disabling  
the use of PyCrust in my application for now -- but it'd be good to  
be able to fix this properly.

Thanks,

  - Erik.
