ghostscript update not automatically activated

[joerg van den hoff]

I ran `port upgrade outdated' today. after end of sucessfull completion

`port outdated' still reported

     ghostscript                    9.27_1 < 9.50_0


rerunning the `upgrade' did not change anything. on further inspection I see that I now have

  1) ghostscript @9.25_1+x11
  2) ghostscript @9.26_0+x11
  3) ghostscript @9.27_1+x11 (active)
  4) ghostscript @9.50_0+x11


question1: why does this happen? should not the `upgrade' take care of deactivating/activating 
automaticall? it usually does...

question2: `deactivate ghostscript' warns me (not quite unexpectedly) that multiple ports will 
break. how to proceed? force activation of ghostscript and rerun `upgrade'?

thank you
