Mac OS X pygame input goes to Terminal instead of Python

I'm having trouble running a pygame based app on Mac OS X via Terminal. Input events such as keystrokes go to the Terminal instead of my Python app, and are detected by pygame. For example, I have the following test script: ``` import pygame pygame.init() screen = pygame.display.set_mode((640, 480)) done = False while not done: pygame.event.pump() keys = pygame.key.get_pressed() if keys[pygame.K_ESCAPE]: done = True if keys[pygame.K_SPACE]: print "got here" ``` Neither K_ESCAPE nor K_SPACE will be handled by this script when I run it from a Mac OS X Terminal, but Terminal will echo back the spaces. I'm running the MacPorts port of pygame (py-game), which depends on Python 2.4, and I've also used python_select to make python24 the active version.
