I know it. :) I had my own similar script "ports_tree.sh" to show me 
dependencies according to choosen options. I know it is too verbose and 
I use grep -v to exclude known packages from the output. The same will 
apply to pkg_tree.sh as well. I use pkg info -r, pkg info -d or pkg 
query often. The request for port of pkg_tree.sh has not high priority 
for me, it is just that this shell version is better than already 
existing pkg_tree in Perl. (which I don't use)
