After a bit of googling around, I see this issue is pretty common but has no direct answers.
Trying to use Pycrypto on my Mac 10.8.5. Installed it through Pip, Easy_install, and manually with setup.py yet when I try to import it, it says it can't find the module. 
Anyone else have an issue like this?
For those having this issue on Mac, for something reason Pip, easy_install, and even doing it manually installs Crypto with a lowercase 'c' in to site-packages. By browsing in to site-packages and renaming 'crypto' to 'Crypto', it solves the issues with other libaries.
Python - Crypto.Cipher/Pycrypto on Mac?
