Baffled by output from `port dependents'

I'm wondering on this too. It seems like I'm getting some left-over  
cruft:

$ port dependents expat | grep apr-util
apr-util depends on expat
apr-util depends on expat
apr-util depends on expat
apr-util depends on expat
apr-util depends on expat
apr-util depends on expat
apr-util depends on expat

$ port installed apr-util
The following ports are currently installed:
   apr-util @1.2.8_1 (active)

So where do the other six dependents come from? Do I just have stale  
entries in my port registry? Is the dependents command repeating on  
the same entry? Should dependents include the version number?

$ find /opt/local/var/db/dports -name apr-util-*
/opt/local/var/db/dports/distfiles/apr-util/apr-util-1.2.7.tar.bz2
/opt/local/var/db/dports/distfiles/apr-util/apr-util-1.2.8.tar.bz2
/opt/local/var/db/dports/packages/darwin/powerpc/apr- 
util-1.2.8_1.powerpc.tgz
/opt/local/var/db/dports/software/apr-util/1.2.8_1/opt/local/lib/ 
pkgconfig/apr-util-1.pc

I certainly find the output rather ambiguous.
