The system already says "skipping <x> due to missing <y>"
The paths are not /exactly/ represented, but you can figure them out from
<x> and <y>.

If you want something more-sophisticated than what it's doing now, it'll
have to wait. However, this is one of those things that really needs core
Jam enhancements in order to do it right. That's why the requirements
document we discussed would be a big help - we need to gather all the
required behaviors in one place so we can see what needs to be
