I can see that.

But Python 2.6 must not care about whether the 10.4SDK
exists or not. It must be using 10.5 or 10.6 since they
are te only SDKs that do exist.

As far as different sources, only one set is supplied and
it specifically states in the comments that the source
supports 3.x. There are, after all, 3.1 versions of the
windows installer.

I certainly woudn't be surprised by the need for seperate
sources, but wouldn't such seperate sources have been
supplied and seperate setup scripts been provided?
