Mike, I've just gotten nltk to work on my iMac. I was having the exact same
problem as you. Perhaps you've already fixed this issue--but maybe someone
else will have the problem, too. 

1. First, you need to install PyYAML, here: http://www.nltk.org/download
(scroll down to where it says install PyYAML). Remember where you extract
2. Then, boot up terminal, direct terminal to the correct directory (i.e. cd
/Applications/PyYAML...) and then do: sudo python setup.py install. PyYAML
will install. 
3. After it's installed, direct terminal to the correct directory where
NLTK's setup.py file is located (i.e. cd /Applications/Python\
2.6/tmp/nltk-installer/...) and then do: sudo python setup.py install. NLTK
will install. 
4. Check this by then typing python into terminal and: import nltk at the
prompt. Like the NLTK site says, if after typing import nltk at  the prompt
(>>>) returns silently, your installation was successful. 

Feel free to email me if this doesn't work or you need more help.
