Dep tree monitor??

[mmuser]

This post is related to a previous problem I had posted in another forum.

Is there anything in portage that monitors whether you update a dep lib of another installed program and either complains or recompiles packages built on older version of the libs? or is this something that we should have to keep track of ourselves?

Thanks
