You can always play with 
http://www.lpthe.jussieu.fr/~talon/pkgupgrade
which, i think, is a lot easier to hack than portupgrade, and includes,
like portupgrade, a dependency graph computation. Beware that there is 
not a unique way to compute the upgrade order, so you cannot be sure to
get an optimal way. In a few words, the problem is to get a total order
on a set of ports compatible with a partial order given by dependency.
There is always such a total order, but it is not unique.
