            if not sys.platform.startswith('java'):
                warnings.warn(
                    "\nYou don't have the C version of NameMapper installed! "
                    "I'm disabling Cheetah's useStackFrames option as it is "
                    "painfully slow with the Python version of NameMapper. "
                    "You should get a copy of Cheetah with the compiled C version of NameMapper."
            self.setSetting('useStackFrames', False)
