PyTTS incompatibility with Python 2.4

When I try to use PyTTS with Python 2.4, I get

Traceback (most recent call last):
  File "tts.py", line 3, in ?
    tts = pyTTS.Create()
  File "C:\Python23\Lib\site-packages\pyTTS\__init__.py", line 28, in Create
    raise ValueError('"%s" not supported' % api)
ValueError: "SAPI" not supported

Digging deeper I see that the actual exception is quite different (alas, the perils of eating exceptions):

Traceback (most recent call last):
  File "tts.py", line 1, in ?
    import pyTTS
  File "C:\Python24\lib\site-packages\pyTTS\__init__.py", line 4, in ?
    import sapi

C04F8EE628x0x5x0.py", line 1192
    """Add"""
    ^
SyntaxError: invalid syntax

Anyway, I don't have any problems when I use PyTTS with Python 2.3
