Peter,

Yes. I got a clue when I saw Numpy (which worked (has a AMD64 build)). and
failed when switched to and earlier python level (2.6 -> 2.5). Numpy only
has a Win32 installer, and it reported the same failure with the
python-2.5-amd64 registry values.

If I can, I will prepare (the libraries?) for a Biopython-2.x-AMD64 package.
I haven't installed a C/C++ build environment on my windows machine (yet),
but; I'm adept at Linux and Windows C/C++ development. And, I'd like to have
a 64bit Biopython <smile>. From your email, I now assume Biopython is not
strictly python code (which should run on whatever python is installed).

I'll dig into the source + documentation, but you probably can give me the
short answer. Does this build from a GCC on windows (e.g. Cygwin or
GnuWin32), or a Microsoft build environment (e.g. Visual C++)? And, I assume
it is not cross-platform prepared from Linux (e.g. fake-root)? Thanks.
