You should definitely run sudo xcode-select -switch /Applications/Xcode.app like everyone here says, that'll fix many problems, but certainly not all.

Afaik, all the remaining problems exist within the configuration information for various packages. You might simply reinstall MacPorts as described in the migration instructions, but I found another solution.

You should begin finding all effected port files using commands like grep /Developer/ ..., after executing sudo bash and cd /opt/local naturally.

You should identify all effected ports by using port provides ..., which I piped through sed and sort | uniq. You could simply reinstall all these ports using either port -n upgrade --force ... or separate port uninstall ... and port install ... commands.

I recommend using one large port -n upgrade --force ... command to avoid duplicate rebuilds of dependencies, using the separate uninstall and install commands afterwards.

There are of course various ports for which /Developer exists only inside text config files, meaning you can fix them manually with sed -i -e 's/\/Developer//g' ..., but you cannot do so with binaries obviously.

I'm afraid you must at minimum rebuild all your Python and Perl installations, making this upgrade an ideal time to clean out packages that depend upon older versions, ala python26 and perl5.8.

There are several technically effected ports I decided against rebuilding like fuse4x-kext, who contained /Developer inside Library/Extensions/fuse4x.kext/Contents/MacOS/fuse4x but hasn't prevented sshfs from working correctly.
