Hello! I'm happy to announce that all four additional components (python-zope.interface, python-twisted, cloudeebus and pycrosswalk) are now available as community maintained packages [1] in Tizen. Setting up the git trees took a while.
Currently they get compiled for Common and IVI: https://build.tizen.org/project/show?project=Contrib%3AIVI https://build.tizen.org/project/show?project=Contrib%3AMobile The repositories are under: http://download.tizen.org/live/Contrib:/ Note that I have not actually tested the new binaries with a current Tizen installation. Feedback welcome.
