wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface simply and easily. It is implemented as a Python extension module (native code) that wraps the popular wxWidgets cross platform GUI library which is written in C++. If you want support for gnomeprint pass GNOMEPRINT=yes to the script. This will require libgnomeprint and libgnomeprintui, both available from SlackBuilds.org. Building the media library, which provides bindings for gstreamer, requires GConf. This package conflicts with wxGTK because it's already included in wxPython. Both cannot be installed at the same time!
