Moving /opt/local aside is not sufficient to uninstall MacPorts. See  
proper uninstall instructions here:

MacPorts doesn't include a command to help you rebuild an entire  
installation like this. This is unfortunate and makes it a rather  
involved process. But since upgrading to a new major OS version is a  
task users don't perform often, I don't think any work has gone into  
making this easier.


I think the key to solving this would be to have MacPorts record more  
information in the registry about each port that was installed,  
including what version of Mac OS X it was done on, with what version  
of Xcode, and even record several of the settings from macports.conf  
that were in effect at the time. Then we can make "port outdated"  
recognize that if the current OS is a major version later than the  
one a port was installed with, the port needs to be rebuilt.
