error install basemap on mac

[admin]

I follow the setup from this link: <a href="http://peak5390.wordpress.com/2012/...p-tutorial-installing-matplotlib-and-basemap/" rel="nofollow">http://peak5390.wordpress.com/2012/...p-tutorial-installing-matplotlib-and-basemap/</a>

However, after I finish all the process. I still encounter error trying to import basemap module.
The error message is like the following:
from mpl_toolkits.basemap import Basemap
ImportError: No module named basemap

Thanks!
