Thanks, that works for me. I marked ticket #20887 resolved.

Maybe you could take a look at #20896 too? Though there we're not  
talking about something that has never worked before (non-root install  
on Snow Leopard); we're talking about something that used to work in  
MacPorts 1.7.1 (non-root install on Tiger and Leopard). So I don't  
think it'll be the same solution. Rather I guess this might be fallout  
from the GSoC '08 privileges branch.
