I've hosed my ports install, clean slate install?

I did a similar migration recently. The best thing to do is probably  
to move all of /opt aside (I moved mine to /opt-ppc) and then just  
start over, first installing MacPorts 1.4.0 from the disk image, then  
selfupdating it to 1.4.42, and port installing the ports you want.  
Then you can move over any configuration files you had changed in / 
opt-ppc to /opt. (Check /opt-ppc/local/etc for sure, and other places  
specific to your ports -- for example, if you use apache2, check /opt- 
ppc/local/apache2/conf. If you use mysql5, check /opt-ppc/local/var/ 
db/mysql5.) Finally you can delete /opt-ppc when you're sure you got  
everything of value out of it. I kept mine around for a couple months  
just to be sure, though it did use up a bit of disk space.

You may also have things outside of /opt. This FAQ entry shows you  
how to completely remove all of MacPorts (usually); the directories  
in the shown command are where the other parts might be located:
