    You are missing the python development headers, needed to build packages that need to compile extensions.

    If you are building on OSX, make sure you either install a prebuilt mac python package or if building python from source, use the framework flag when configuring. And also make sure you have XCODE installed so that you have a compiler.

    If you are building on Linux, you probably need to install the python devel headers. For instance on Ubuntu you would need: apt-get install build-essential python-dev.
    Once you have the python development headers, twisted should be able to find them when you build with that python interpreter.
