There is a longstanding issue...

If you have a server running and you upgrade the port, then the old  
plist (that says the server was running) gets removed (because it's  
part of the files installed by the port) and the new plist that gets  
installed says the server isn't running, though it still is.

We added "port load" and "port unload" to 1.7. What I think we should  
still do is call "port unload" automatically before we call "port  
deactivate" (if the port was loaded), and then after "port activate",  
we should automatically call "port load" (if the port was previously  
loaded).
