There's no such directory in a standard MacPorts install... There is /opt/local/etc/macports, /opt/local/share/macports, and /opt/local/var/macports.

By saving the list of installed ports, should your MacPorts installation become so garbled that the "port" command can no longer run or can no longer read the registry of installed ports, you could nuke your MacPorts install using the uninstallation instructions in the Guide, and then use the reinstallation script on the Migration page to reinstall the ports based on the myports.txt file.

I mentioned the Migration page not because you're migrating between OS releases but because it discusses how to reinstall a set of ports, which is what you asked how to do.
