Here are some hints for popular operating systems:

If you are seeing this message on Linux you probably need to
install GCC and/or the Python development package for your
version of Python.

Debian and Ubuntu users should issue the following command:

    $ sudo apt-get install build-essential python-dev

RedHat, CentOS, and Fedora users should issue the following command:

    $ sudo yum install gcc python-devel

If you are seeing this message on OSX please read the documentation
