Installing NLTK to Mountain Lion

NLTK 



Just leave some memo as I stacked to install NLTK into my Macbook Pro (Mountain Lion). Please note this is not a complete guidance, but just to mention points where I stacked.
1. Python must be re-installed even if Mac-python is available
In my Macbook Pro, Python 2.7 was pre-installed but I faced several problems when installing NLTK and related tools. Most of the problem was solved by installing "Standard" Python downloaded from python.org.
2. XQuartz need to be installed
At the beginning I forgot to install this, I got an error in ft2font.so when installing matplotlib. After installing XQuarts, the error gone. Maybe most of experienced guys already know but I missed this as I am a newbie. XQuartz installation can be done with GUI.
3. Numpy is missing?
(After installed XQuartz) I started to install matplotlib. However, "Could not find the header for numpy" in the log.
