It should. It use the pkg_summary database to make sure dependencies are 
correct, there aren't conflicts, there is enough space to download and 
install, and that shared libraries are provided. Then it downloads all 
dependencies before it begins. Note it needs the packages' metadata 
built with recording this shared libraries provided or required if that 
is desired.  pkgin has had some problems for me, but it has also been a 
good timesaver. Probably with more use and more feedback, it can be 
improved.

As for Debian, if you have any details on the stages you can point me to 
that would be great. (I do use apt-get but it has been a while since I 
studied it.)
