Hi everyone,
I'm trying the very simple examples listed in the plotting section of
the tutorial, however every time I try a p.save() or a p.show() I get
the output below. I've installed and played around with python2.5 and
I can plot just by going to a terminal and doing plot(x), but there
seems to be something wrong with the matplotlib in the SAGE directory
tree?
help is appreciated.

sage: p.show()
