Does anyone know how to configure the hunpos wrapper class on nltk?

i've tried the following code and installed from http://code.google.com/p/hunpos/downloads/list

english-wsj-1.0

hunpos-1.0-linux.tgz

i've extracted the file onto '~/' directory

and when i tried the following python code:

import nltk
from nltk.tag import hunpos
from nltk.tag.hunpos import HunposTagger
import os, sys, re, glob
cwd = os.getcwd()

for infile in glob.glob(os.path.join(cwd, '*.txt')):
    (PATH, FILENAME) = os.path.split(infile)
    read = open(infile)
    ht = HunposTagger('english.model')
    ht.tag(read.readline())

i get the following error

Traceback (most recent call last):
  File "<stdin>", line 4, in <module>
  File "/usr/local/lib/python2.6/dist-packages/nltk-2.0b9-py2.6.egg/nltk/tag/hunpos.py", line 46, in __init__
