python-dbus-dev 1.3.2-4build1 (ppc64el binary) in ubuntu lunar

 D-Bus is a message bus, used for sending messages between applications.
 Conceptually, it fits somewhere in between raw sockets and CORBA in
 terms of complexity.
 .
 This package provides development files required to compile main-loop
 integration modules for python3-dbus, such as dbus.mainloop.pyqt5 provided
 by PyQt. It is Python-version-independent, and was shared between Python 3
 and Python 2 when Python 2 was supported in Debian, so packages that
 build-depend on python-dbus-dev should also build-depend on python3-dbus.
