port dependents foo

[Lenore Horner]

I would have expected port dependents foo to tell me all the things  
that depend in any way on foo.  If I understand correctly what I am  
seeing, it tells me only what has run-time dependencies on foo.  I can  
understand that after installing bar it would be safe to uninstall foo  
if bar had only a build dependency on it.   However, what if bar has a  
library dependency on foo?  If I uninstall foo does that kill its  
libraries breaking bar or does it leave behind all the libraries in  
which case how does one keep from ending up with a hopelessly  
cluttered system?
