I don't think it should be. Most daemons write their pid (process ID)
to a pid-file on startup.  When you stop an rc script it reads the
pid-file and checks to see that there is a process with that pid and
which has the correct command line. If no match is found you get that
warning. Reinstalling a port shouldn't affect the pid file.
