I ve searched far and wide, read a previous question in stackoverflow but cant seem to solve the problem of installing rpy2 on my Mac with OS X 10.5.8. I have Xcode 3.1.4 installed and R 2.1.11. when I run:

sudo python setup.py build install

我明白了：

running build
running build_py
running build_ext
building  rpy2.rinterface.rinterface  extension
