Yes, "port installed" answers this question. "port list installed" is  
something many people try but almost never produces the result they  
expect. (It does "the correct thing" but most people don't know what  
"port list" is meant to do. It lists the current version available,  
which is not necessarily the same thing as the version that's  
installed, which is what most people want to know.)

You can feel free to check out the guide sources from Subversion

http://svn.macports.org/repository/macports/trunk/doc-new/guide/

and submit a patch in a ticket in Trac if you have changes.

I'd be surprised if "port installed" were not already described in  
the Guide...
