Error installing rpy2 2.2.1 on Mac OS X 10.6.8

I am trying to install rpy2 from a downloaded source archive 'rpy2-2.2.1.tar.gz'. I have been following the installation instructions provided from the rpy2 documentation. This is what I am doing:

    tar -xzf rpy2-2.2.1.tar.gz
    cd ~/Desktop/rpy2-2.2.1
    python setup.py build install

And here is the output in terminal of the attempt:

If the make command is missing, chances are you need to install the Apple Xcode Developer Tools. There should be an installer for Xcode 3 somewhere on the DVD or other material that came with your Mac or copy of OS X 10.6. Or you can download it from the Apple Developer Connection website (free membership required). Or you can purchase Xcode 4 from the Mac App Store.


I am receiving the same error. But I am using the Easy_install. The Setup.py is what is generating the error. I only got a brief chance to examine the setup.py file last night, but I think I have figured it out.

This is what I am pursuing right now. The newest version of R, 2.13.1, appears to have added an additional directory layer to the R_Home Path. I suspect that the setup.py for the rpy2 is not expecting this difference and is not able to get past it. I will be investigating this today.

If it is the case, then I will follow this answer up with my actual fixes and the changed setup.py file.
