I am not sure, but it might be that the message shown above is a bit inaccurate
and it is the "macports" group that is missing?

Please check that the user and group do exist for dscl (Directory Services):

  dscl . -read /Users/macports
  dscl . -read /Groups/macports

In any case, running the MacPorts install either from the .dmg or from source
once again should recreate both the user and group named "macports".
