Hi Edward, this does not work: $ ./relax.app/Contents/MacOS/python Could not find platform independent libraries <prefix> Could not find platform dependent libraries <exec_prefix> Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>] ImportError: No module named site There seems to be a problem with the PATH variables, it doesn't find the needed libraries. I have no idea how to pass these to the local interpreter.
