If you are on OSX, the easiest solution in my opinion to avoid errors like you are having is to use Homebrew to manage the installation of Python, pip and libraries like pandas.

If you are already using Homebrew (it was unclear from your question). Try running brew doctor and see if there are any reported errors.

To get pip working in concert with Homebrew:

• ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)" to install Homebrew.

• brew doctor and make sure you get no errors from running this command. Follow what it recommends, especially concerning the $PATH environment variable.

• brew install python to install Python 2.7 (and pip)

• pip install pandas
