Pextlib 1.0

Hello,

I am trying to install DP on my intel mac mini core duo but am not  
having much luck. I have tried to install from the 1.3.2 sources and  
from the latest CVS snapshot - in both cases, the installation  
finishes without a hitch but when I try to run 'port selfupdate'  (or  
any other command), I get the following error:

Failed to initialize ports system, can't find package Pextlib 1.0

I am not sure what's going on here. I searched the mailing list  
archives and found a bunch of posts with the same problems but no  
solutions. Any advice would be greatly appreciated !!

Thanks in advance,
Nitin
