This of course assumes that there _is_ a correct order, which is not the 
case with circular dependencies.

The reason depinst.py, for instance, is not bothered by the circular 
dependencies is that it doesn't download - build - install one by one; it 
just downloads, so order doesn't matter. Once everything is in place, you 
could then build and install. But in this scenario, libraries don't need to 
find_package each other, they know they are siblings.
