Hi,
As I have written somewhere else a couple of times. If unmerging a part
of the system consider running quickpkg --include-config=y
<forexamplepython> before. Running revdep-rebuild might show you do have
to reinstall whatever you unmerged but emerge might not be able to do it
any longer if something is really broken.
