Yes, 1.0.2 is the version we are using on Linux so I went with that
one. I will try newer version.

The same error was when I was building PIL library, so I had to apply
small patch to msvccompiler.py file in Python's distutils and export
DISTUTILS_USE_SDK and MSSDK env variables to override builtin settings
which were always looking for VS 2003 compiler, then the build process
went without a problem. I followed the instructions described here

With VS 2008. I opened Python-2.5.1\PCbuild8\pcbuild.sln file with
Visual Studio, included project files for tkinter, ssl, bddsb, etc...
and everything was built without problems. I have the full Python
2.5.1 distribution build, identical as the Python-2.5.1.msi
installation from python.org.

Thanks for the info. It would certanly be bad news for me if numpy
really can't be build with VS 2008. I will try with numpy 1.1.1 and
see what happens.
