I've been having trouble with Python, iPython and the libraries. The following points show the chain of the problematics. I'm running Python 2.7 on Mac Lion.
I've tried several things that I've encountered from other blogposts. But none of them have helped, and also unfortunately I don't quite know what I'm doing with some of them. For example: I tried uninstalling and reinstalling ipython with easy_install and pip. I also tried reinstalling everything through homebrew, and modifying the path .bash_profile.
