[tahoe-dev] install error

[F. Carpico]

Hello,

I'm trying to install Tahoe on Windows Vista but when I execute  
"C:\Python27\python setup.py build" I get this error :

Setting up environment to run scripts for the current user...
Already done: associate the filetype .pyscript with Python.File for the  
current user.
Already done: add .pyscript to the user environment variable PATHEXT.
Already done: add .pyw to the user environment variable PATHEXT.

I've installed Python 2.7, mingw-get-inst-20120426, Cygwin last version  
and done all that is described here :
