There is no official build. The only official Win64 build is
for Itanium, see www.python.org/2.4.2

I'm not at all mystified. The operating system was only released
after the release of Python 2.4, there is no official compiler
available yet to the general public, and I don't have the hardware
to test such a release.
It's fairly likely that Python 2.5 will not see official AMD64
Windows binaries, either.

So you should build this on your own.

A number of people have tried this. There is one open issue
with signal handling: VS 2005 will apparently drop compatibility
with Standard C in one aspect where previous releases used to
be C compatible (namely, processing of unsupported signal
numbers in signal(3)). Because of that, Python will raise
an assertion failure in the debug build.
