Hello, I have Python 2.6 and Visual Studio 2008 running on a Win7 x64 machine. When I try to build the basic python extension example in c "example_nt" as found in the python 2.6 sources distribution, it fails:

python setup.py build

And this results in:

running build
running build_ext
building 'aspell' extension
Traceback (most recent call last):
  File "setup.py", line 7, in <module>
    ext_modules = [module1])
  File "C:\Python26\lib\distutils\core.py", line 152, in setup

  File "C:\Python26\lib\distutils\msvc9compiler.py", line 274, in query_vcvarsall
raise ValueError(str(list(result.keys())))
ValueError: [u'path']

What can I do to fix this? Any help will be appreciated
