## Python Issues OSX
Make sure you are using the native Python version in OSX. If you use a MacPorts of HomeBrew version, you may run into problems.
If you have issues with `execvp`, be sure to check your `$PYTHON` environment variable. If it is not set to the native version, unset it and try again.
