I don't know exactly what's the use of portupgrade, but I wrote a small dirty zsh script that writes the dependents of a port and its dependents (recursively). As it may be wanted by some people and may be quite usefull for having a coherent tree when a lib is updated, here it is. There may however be problems of order of rebuild... Hope some will like it, Emmanuel
