Maybe a bug in rst2latex

If I run rst2html test.rst > test.html I obtain a file with the links
correctly setted as one can expect.

But if I run

    $ rst2latex test.rst > test.tex
    $ pdflatex test.tex

I obtain a series of warnings:

    LaTeX Warning: Hyper reference `chunk3' on page 2
    undefined on input line 150.

and the links there are not into the resultin pdf.

I can correct this behaviour adding into "test.tex" a series of macro
"\phantomsection\label{chunk1}", but I think this should be done by rst2latex.

The file "test.tex" has the corrections into a comment block.

The name of this program is "pipe" and has two blocks of code.

.. _chunk1:

::

  <pipe>=
    <Add two terms>
    <Say hallo>

The first block of code takes two parameters and return the sum of
them. Think of it as a ``graeting code`` between two column of beer.

.. _chunk2:

::

  <Add two terms>=
    def add(a, b):
        result = a + b
        return result

*[defines <add> used in chunk3_]*

.

then open the list and return the result.

.. _chunk3:

::

  <Add two terms>+=
        result = result - []
        return result

The second and last block of code takes one parameter, uses the add
function previously defined, and finally say hallo.

.. _chunk4:

::

  <Say hallo>=
    def sayhallo(s):
        v = add(s, s+1)
        print "Hallo %d" % (v)

*[defines <sayhallo>]*

.

So has come the end of the program.
