I spent a few days on this too... then I stumbled upon this thread, where a link is given: http://www.lfd.uci.edu/~gohlke/pythonlibs/#rpy2

On this page you can find (amongst other useful things) a pre-compiled version of rpy2 for Windows, and for different versions of Python. It apparently only works for R 2.15.3, I did not try it with other versions.
