This is part of the functionality of MacPorts: you can have multiple  
versions installed, but only one activated at a time; there will be a  
discussion elsewhere about all the reasons why this is useful, but I  
use it for testing updates to ports without having to have archives  
lying around or waiting for an entire port to rebuild if the one I'm  
working on fails and I need the old one.

To take care of this, you can:

  (1) supply the -u flag to upgrade, which will deactivate and  
uninstall any older versions of a port before installing and  
activating the latest one (this is what I usually do);
  (2) manually deactivate the old port and activate the new one,  
which will leave the old port still installed; or
  (3) manually uninstall the old port and activate the new one, as  
you did, which will remove the old port (but still leave the binary  
archive of it if you have archive mode set in your ports.conf).

This command will only list the latest version of a port as listed in  
PortIndex (of which there will be only one if you are using only one  
repository in your sources.conf).  If you had instead typed "sudo  
port installed grace" after the successful install but failed  
activation, you would have seen something like:

 > sudo port installed grace
The following ports are currently installed:
   grace @5.1.18_0 (active)
   grace @5.1.20_0

(By the way, you don't actually need to sudo port's information  
actions.)

I hope that this clarifies things for you.

Kind regards,
