Hi Xavier,

as suggest by you I'll explain the error and the solution a little bit more in depth:

error 1:

.. _getting-the-introduction-package:     <= forgot to update the
                                             reference text!

correction:

                                             updated!

error 2:

correction:

                                             label and text!

Well, as said before I'm new to ReST and think this is a typical beginner's error when reworking an already existing text.
