Guillaume, does the command underneath work on your distribution?  And
if so, what's the output?

  $ readlink -f "$(which vncviewer)"

Maybe this command is enough to detect the used alternative on any
distribution, i.e. _get_alternative()?  If we do this from within the
completion it's not slowing down completion-installation:

have vncviewer && {
  _vncviewer_bootstrap() {
     case "$(readlink -f "$(which vncviewer)")" in
        *xvnc4viewer) fname=_xnvc4viewer ;;
        *tightvncviewer|*) fname=_tightvncviewer ;;
     esac

     # Install real completion for subsequent completions
     complete -F $fname vncviewer
     $fname  # Generate completions once for now
  }
} && complete -F _vncviewer_bootstrap vncviewer
