So can I use this to remove the +server variant from my already  
installed mysql5

   mysql5 @5.0.85_0+server (active)

which is no longer needed, and reminds me so everytime I do a sudo  
port upgrade mysql5, as it's now handled by the

   mysql5-server @5.0.85_0 (active)

eg
sudo port upgrade --enforce-variants mysql5 -server

or does a "-" not negate a "+"



Is it any worth to do something like
     sudo port upgrade --enforce-variants --force installed
to do a one-hit "mend" of all the missing +darwins
