" This is a "guts of wxPython" thing. Either there's no Xwindow server running, or they forgot to specify "WX GUI" in the generate options."
This may be the problem, I didnt manually specify WX GUI in the generate options. My install was completed by a scripted install via yaourt package manager on Arch Linux, no errors. I assume WX GUI was generated as I can run the WXGUI Waterfall Plot with no errors. Xwindow server is running. I did find a forum post with a reported fix to the problem, do you guys think I should try this? refer to last post in http://nuand.com/forums/viewtopic.php?t=3524&p=5164. I generally avoid trying to downgrade and manually install packages, it'd be better if there was a simpler solution.
