Answer 1

Try:

sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install discount

This seems to be an issue with LLVM in XCode 5.1 as mentioned here: Can't install mysql gem on OS X

Answer 2

If you enter gcc or cc in the terminal, will it output an error? Do you have Xcode installed?

xcode-select....

If so, Mac Os Mavericks should alert you to install Xcode Command Line Tools.
