RPy2 - 2.1.7 Installation problems on WIN XP

Good morning everybody, I'm really struggling during the installation of rpy version 2.1.7 on a windows XP machine. I put the correct path in the environmental variable (C:\R\R-2.10.0\bin called R_HOME). The installation process appear to accept the entry and it does not give the message "no R Command in the PATH" and it starts the installation.

However, after a little while it gives me the folowing e开发者_JAVA百科rror:

File "C:\python26\lib\site-packages\setuptools\package-index.py", line 475, in fetch_distribution return dist.clone(location=self.download(dist.location, tmpdir)) AttributeError: 'NoneType' object has no attribute 'clone'

Is there someone that can please explain to me what does this mean? Many thanks, Fabio
