It works, if you put [declare -path .] into those abstraction of your
foo library, that require the list-abs library.

Mind the the dot, it's not '..', as someone would probably consider more
intuitive. This is because [declare] inside abstractions expands the
path relative to the topmost parent patch's location, not relative to
the abstractions own location. 

This example really works only when the main patch is in the same folder
as your optionally shipped list-abs library.

Even if this solves your initial problem, I wouldn't use this solution,
because in order for it to work correctly, your abstractions from foo
need to make an assumption about the relative path between the topmost
parent patch and the list-abs directory.
