I am trying to install 4Suite-XML 1.02 on my Linux Mint 17.2 Cinnamon. I downloaded the tar.gz, extracted it, opened a terminal in the extracted directory, shifted to root shell with sudo su, and ran python setup.py install. I get this as output:
running install
running build
running config
running build_py
running build_ext

Usually Linux distributions split programming language run-times to two packages and Python is no exception.
python - Python code runtime
python-dev - Development files, libraries and headers. Needed to install any native extensions. Aimed for developers. Something that integrates Python to "native" C libraries. Python code is portable across operating systems, C code is not. C code must be recompiled to every operating system.
You need to install related python-dev package which contains C headers necessary to compile Python native extensions. This command is usually sudo apt install python-dev on Debian based distributions. I have not checked the actual command for Mint Linux, but I assume it to be the same.
Also please read the official Python package installation guide https://packaging.python.org/en/latest/installing.html - usually sudo installations and python setup.py install are unnecessary. pip install --user command should be able to download, extract and install the package for you.
