Building on Python 2.4

[Martin Aspeli]

Hi folks,

I want to start using Windmill with Plone. There's even an integration
package: http://pypi.python.org/pypi/niteoweb.windmill.

Now, the stable Plone 3.x is still using Python 2.4. There's also the
soon-to-go-alpha Plone 4, which runs on Python 2.6. I'm able to run
Windmill on the latter, but not on Python 2.4. I'm using Mac OSX 10.6
(Snow Leopard).

I think the problem is the ctypes module. Here's what happens when I
try to install the windmill egg in a virtualenv. The best of my
Googling is failing to find the cause of this. Does anyone have any
clues?

Cheers,
Martin

You might try asking ctypes-users (https://lists.sourceforge.net/lists/listinfo/ctypes-users).  I've had no trouble building with OS X 10.5; I haven't tried 10.6 yet.
