Right now I'm seeing that @preserved-rebuild and revdep-rebuild want
to do different things. revdep-rebuild is rebuilding nss which may or
may not fail. @preserved-rebuild wanted to rebuild eveolution which
did fail.

I'm somewhat unclear as to how to proceed. Using emerge is currently
telling me I should do an emerge -e world to fully take advantage of
new features in portage-2.2. I guess that message wouldn't be there
unless it was really a good thing to do but that's a lot of downtime
for me.
