[lxml-dev] cython + python2.4 problem (was: objectify factories)

Lazy me, not like you hadn't announced that quite a while ago.
However, unfortunately: 
Just downloaded cython and tried to build lxml:

0 lb54320 at adevp02 .../lxml $ /apps/pydev/bin/python2.4 setup.py build
Traceback (most recent call last):
  File "setup.py", line 28, in ?
    import setupinfo
  File "/data/pydev/hjoukl/LXML/lxml/setupinfo.py", line 5, in ?
    from Cython.Distutils import build_ext as build_pyx
[...]
  File "/apps/pydev/lib/python2.4/site-packages/Cython/Compiler/TypeSlots.py", line 88
    full_args = "O" + self.fixed_arg_format if self.has_dummy_arg else self.fixed_arg_format
                                             ^
SyntaxError: invalid syntax

Seems like cython relies on Python2.5 syntax, which renders it unusable for me. Any chance to remove the hard 2.5-syntax-dependency? At a quick glance this seems to be the only place where conditional expressions turn up.
