setup.py exits with zero exit code when failing about pygame HOT 2 CLOSED

Original comment by Thomas Kluyver (Bitbucket: takluyver, GitHub: takluyver):

Exit with status 1 if sdl-config missing

sys.exit() with a message == print the message and exit with code 1.

Raising SystemExit also works, but it only gives code 1 if it has a message.

Closes #35

The config system should probably exit with an error code if it can not find the required dependencies. I'm not sure what affect this would have on various build systems, since it is quite a change. However, I think it probably should be a hard fail if the dependencies can not be found.

I think this would make it easier on people to notice that they have forgotten to install a dependency.
