Installing WebPython is very simple. Once the prerequisites are installed (or, better yet, if they are included on your system) just unpack and install WebPython with the following commands:
tar -xvzf WebPython-0.6.0.tar.gz cd WebPython-0.6.0/ su -c "cp webpython /usr/local/bin" su -c "cp -r WebPython /usr/lib/python-X.X/site-packages/"
It will be necessary to replace the X's in the destination directory with your actual Python version number.
su will of course ask you for your root password, which is needed as WebPython should be installed in the global Python site-packages directory.
