I understand "missing," but what does "and dying" mean in this context?
Also, I'm very curious to know if a lot of people are having problems with
failed installs often enough to make this an issue. Personally, it's
extremely rare for me to encounter a failed install (as opposed to a
failed build, which is relatively more common, but not fatal in the
portmaster context).

I'm starting to think that the way to handle this would be to have the
backup option be on by default, and document the process for recovering
from a failed install thoroughly in the man page. Then if that happens, I
can print a message that refers the user to the man page for recovery
details.

Does that sound reasonable?
