Any conclusions there?
I'm not sure it really matters for these purposes what a particular
distribution's package pulls in, if they are happy with what works for
them for the distribution build or bootstrap. The question for us would
be more about what constraints this imposes on distributions in general
(e.g. if it means libffi will be needed for a native build of glibc,
depending on how far the indirect dependencies on ctypes in the Python
standard library go), and whether we are OK with those constraints. The
dependencies of the minimal distribution packages are simply useful
information for us to help in determining those constraints.
