nltk is looking for a module called numarray that is not part of the standard Python distribution. Do you have numarray installed? Look for C:\Python24\Lib\site-packages\numarray. If you don't have it then download numarray from C:\Python24\Lib\site-packages\numarray and install it according to the instructions.
