I've found pkg_tree to be useful for that.
http://www.freebsd.org/cgi/url.cgi?ports/ports-mgmt/pkg_tree/pkg-descr

The feature I use the most is pkg_tree -tq which gives a list of all 
ports that are not depended on by any other ports, i.e. the minimal set 
to manually reinstall to replicate a set of installed ports on another 
machine.
