Well, considering that we plan to use pkg for dependencies and conflicts
resolving what's the real purpose of having 3 alternative systems of
ports management? I really have no understanding why do we want to
complicate things that are already complicated?

Look at the macports, their user shell is perfect: you have no
difference between building software from sources and getting it from
repository. However, you can use only source packages while the default
behaviour is to choose binary packages.

I'm not talking about the current situation when pkg cannot work with
ports and source packages. But eventually we want to implement that
feature and use pkg as the only solver for both ports and binary
packages. In this situation I consider portupgrade and portmaster as a
confusing evil: a user can easily break his system by improper usage of
such tools.
