I just thought about some other possible fix that I never tried. Run this 
command in the same shell used to start pd, before starting pd:

   export LD_PRELOAD=/usr/lib/libstdc++.so

don't use this exact command, use it for each version of the lib you have. 
e.g. on my computer, I'd try:

   export LD_PRELOAD=/usr/lib/libstdc++.so.5
   pd examples/nervous_video.pd
   export LD_PRELOAD=/usr/lib/libstdc++.so.6
   pd examples/nervous_video.pd

maybe I'm completely mistaken about LD_PRELOAD, or that I'm missing 
something else, but I can't test it at the moment.

But even if this happens to work, I'd still rather have a tweak that I'd 
do to GridFlow so that users don't have to do it at all.
