Once a headless version of bdiana has been built, it is possible to build a set of Python bindings specifically for that version. These will reside under /opt/qt4-headless alongside the Qt 4 libraries already built.
We build an alternative set of PyQt bindings using the PyQt 4.9.4 sources and a set of patches. We also need to build a corresponding version of sip that makes fewer assumptions about the system it is running on.
