Gene ,
this is the section , i think giving the problem
if options.window:
reparent(window, xid)
w = builder.get_object('chain_gl_widget')
self.glwidget = w
if options.chain:
w.load_from_str(open(options.chain).read())
self.chain_file = options.chain
else:
w.set_chain(self.create_chain(options))
self.chain_file = None
c = w.get_chain()
c.attach_glib(1000, None)
just need to understand it a bit more , i presume it's looking for the
graphics lib which
in your case is changed from the freeimage lib
i may be wrong of course , as usual
