duplicate listing of ports by `port list installed'

[j. van den hoff]

I have seen this already with 10.6 and currently with 10.8:

`port list installed' frequently reports several of the installed ports  
repeatedly (I see 2-4 times) on consecutive lines (including the  
`@num.num' version designation, i.e. seemingly exact duplicates). which  
ports are affected looks erratic if I compare macports installation on  
different machines. it only seems to be the case that there are more  
duplicates on older macports installations.

I have these questions:

1.
the duplicate listings do not hint at any relevant corruption of my  
macports setup, right?

2.
what is the reason for the occurrence of the duplicate listings?

3.
is there a way to get rid of the duplicates?


thanks in advance
