Don't assume that when pkg(8) wants to reinstall a package that it is
doing it for no reason.  Frequently it's necessary because one of the
shared libraries linked against by the package binaries has changed ABI
and the binary won't actually work properly unless recompiled against
the new version.

However, other times it is less important -- perhaps the dependency
package had a version bump but since pkg(8) has no way of knowing what
is important in the interaction between the two packages, it plays safe
and reinstalls whenever the dependency changes.  Ideally in this sort if
situation the 'reinstall' should do very little other than adjusting the
dependency info in the package DB, plus any binaries or other files that
have changed when compiled against the new dependency -- but that
requires 'repeatable builds' in order to work properly.
