cannot find vcvarsall.bat when trying to build Python libraries.  Python 2.7 is built with the Visual Studio 2008 compiler and so extension modules must be build with the same compiler.  So install VS C++ 2008 Express which will set the VS90COMNTOOLS environment variable.
  http://go.microsoft.com/?linkid=7729279 - by default this version will only give you a 32-bit compiler - so it will only work for installing into a 32-bit Python.

  Update for x64 Compilers: By default this will only give you a 32-bit compiler. I learned (from here and here) that you can download specifically the Windows SDK for Windows 7 and .NET Framework 3.5 SP1 which gives you a x64 compiler for VC++ 2008 (VC++ 9.0) if you need it. Just when you are installed it, you can uncheck everything except Developer Tools >> Visual C++ Compilers which will keep you from installing all the extra SDK tools that you may not need.
