Many thanks. Got it all working. How I would have known that
dispersion.py was trying to import pylab I can't imagine; it doesn't
appear anywhere in the traceback. But now I know and can plot along.
I will do the NLTK list too.

ValueError: The plot function requires the matplotlib package.See

dispersion.py is trying to import pylab. So you could try "import
pylab" in Python and see what error you get.
Also you could try and plot something:
from pylab import plot
x = range(1)
plot(x,x)
But I do think either the NLTK or matplotlib mailing lists would be
more appropriate for you to get help with this.
Also I'd recommend using ipython if you want to work with matplotlib
plots interactively. It's an interpreter that has much nicer behaviour
for interactive work.
Cheers
