Today's update of rakudo+nqp+moarvm left a big mess, after trying
several things and purging everything perl6 related an reinstalling
it looks like:

rakudo+nqp+moarvm can be upgraded or newly installed, but the
handling of the perl6-* modules fails:

Setting up perl6-zef (0.8.5-2) ...

/usr/share/perl6/tools/install-dist.p6 is in rakudo, and I think CompUnit::Repository::Staging
should be in rakudo as well but is not there or is not found.


Cheers,
