Just reinstalling MacPorts would not affect installed ports. The Migration
stuff (https://trac.macports.org/wiki/Migration) would involve removing and
reinstalling ports.

I suppose you could just reinstall the MacPorts base and then verify that
all active ports have all their files. Reinstall any ports that report
missing files.

    oIFS="$IFS"
    # note that this is a single newline in single quotes
    IFS='
'
    for port in $(port -q echo active); do
      for file in $(port -q contents "$port" | sed -n 's/^  //p'); do
        test -e "$file" || echo "MISSING from $port: $file"
      done
    done
    IFS="$oIFS"
