Hi,
I think this pythonw thing works for me only because I'm on osx and there is a
/usr/bin/pythonw, which means "run python with a gui", so it is
running a system-wide
python. However, because I did "sage -sh", I'm still getting the
packages installed
into sage, e.g., pyglet and sympy.
So folks, don't try this at home after all. That said, it's very
pretty when it works,
so we should definitely figure out if pyglet can somehow benefit sage.
