Nice to hear! Feel free to try out upt. It should even be able to
package itself, which should make it easy to include it in your ports
tree :)

Yes, but some external dependencies are never specified, if I'm not
mistaken. For instance, the pbr package depends on the "git" binary, and
I do not think there is any easy way to know that. My tool (just like
all other tools) can only gather data provided by the frontends, which
is not always enough.
