There is a tool called pkg_rolling-replace (pkg_RR for short) available
that many people find useful for updating. It can be installed from
pkgtools/pkg_rolling-replace.

just running "pkg_rolling-replace -uv" should update everything with
as little rebuilding as possible.
If you don't mind a small bit of unnecessary rebuilding as a tradeof for
always getting correct shared library dependencies, then you can run it
with "-rsuv" (which is what I do). See the manpage for an explanation
of the options.
