Re: [orca-list] Problem with PYTHONPATH and multiple versions of orca

[Willie Walker <William Walker Sun COM>]

I'm not quite sure I understand how this stuff is actually getting in 
the way.  My understanding is that PYTHONPATH should be considered 
first.  Is it possible that PYTHONPATH has been defined in your local 
environment?  The orca script adds itself to the end of the PYTHONPATH 
environment variable, so if you have PYTHONPATH set up already, it 
might end up picking up that.  As for why orca adds itself to the end 
rather than the beginning, see 
http://bugzilla.gnome.org/show_bug.cgi?id=491417.
