Yes, MacPorts itself is now installed correctly for Snow Leopard. But  
all the ports you already have installed are still installed in a way  
that was correct for Leopard, but is incorrect for Snow Leopard.

As explained in the "Reinstall Xcode and MacPorts" section of the  
Migration page, you need to reinstall MacPorts and Xcode. You've  
reinstalled MacPorts using the .dmg -- good. Have you also installed  
the latest Xcode? Version 3.2 should be on your Snow Leopard DVD, or  
you can download version 3.2.1 from Apple.

After you do that, you can use the commands in the "Reinstall ports"  
section of the Migration page to reinstall your ports.
