This might be a bad idea, because:

- a port might not run well when deinstalled (even when it does on the 
porters machine, it might fail in a different configuration)
   generally I think daemons should be terminated before deinstalling the 
port

- the configuration files might be incompatible with the new version

Generally, you can achieve this effect with portupgrade(1) (see 
BEFOREBUILD/AFTERINSTALL in pkgtools.conf(5)). What might be useful 
could be a `make start|stop|restart'.
