IPython is not a version of Python; it is simply a front-end to the  
interactive Python prompt which makes it more pleasant to use (it adds  
tab completion, for example, and allows you to keep using the prompt  
while displaying a plot (e.g., to add things to an existing plot  
window, or to open multiple plots). IPython and NLTK will not  
interfere with one another.

At any rate, the matplotlib error is not an error but a warning, and  
unless you are making plots that involve dates and/or time zones  
(which is improbable given the subject area), it can be safely ignored.
