Ah yes indeed, this is another thing I've messed up in the next branch and
haven't had a chance to fix yet :)

I made a good chunk of changes without checking Hudson to see how they were
performing on other versions of Python and other platforms. This past weekend I
went back to Hudson and realized my error.

You can check out the current build results here:

My apologies, I typically work under Python 2.6 so I was completely oblivious
to the breakages on Python 2.4 and 2.5

I'll probably fix it tonight or tomorrow sometime; I'll update the thread when
it's there
