To me, it makes more sense to have path: search $PATH (or if it's an absolute path, just look for that specific file).

My preference would be to have path: work this way, and bin search only inside $prefix.

I'm not aware of an instance where we want outside lib's to fulfill dependencies (any more), though - so lib: should probably be changed to just look in $prefix.
