Comment (by wluebbe):
I finally manage to run the doctests with the Python command line option
{{{-3}}}. This is how I did it:
{{{
...:~/sage-6.2.beta8$ . src/bin/sage-env
...:~/sage-6.2.beta8$ python -3 ./local/bin/sage-runtests src/sage 1>logs
/sage-warnings3-stdout.txt 2>logs/sage-warnings3-stderr.txt
}}}
A summary of {{{stderr}}} output is
{{{
nbr_lines= 133
83 Overriding __eq__ blocks inheritance of __hash__ in 3.x
27 classic int division
18 type inequality comparisons not supported in 3.x
2 the cmp argument is not supported in 3.x
1 execfile() not supported in 3.x; use exec()
1 file.softspace not supported in 3.x
1 tmpfile has been removed in 3.x; use the tempfile module
}}}
and of {{{stdout}}}

instead.

2 Use the Permutations object instead.
2 This class is replaced by
Matrix_modn_dense_float/Matrix_modn_dense_double.
2 to_permutation() is deprecated. Use instead
reading_word_permutation()
2 this class is deprecated. Use RibbonShapedTableau instead
2 BaseException.message has been deprecated as of Python 2.6
2 The 'new' module has been removed in Python 3.0; use the 'types'
module instead.
2 this is done automatically by the doctest framework
2 derangements() is deprecated. Use Derangements instead.
1 The output of Transducer.cartesian_product will change. Please use
Transducer.intersection for the original output.
1 Substitution using function-call syntax and unnamed arguments is
deprecated and will be removed from a future release of Sage; you can use
named arguments instead, like EXPR(x=..., y=...)
1 This method is deprecated. Use triangulate() instead.
1 In 3.x, reload() is renamed to imp.reload()
1 dict.has_key() not supported in 3.x; use the in operator
1 The output of
1 Substitution using
1 This method is deprecated. Use triangulate().simplicial_complex()
instead.
1 Variable of integration should be specified explicitly.
1 OrderedAlphabet is deprecated; use Alphabet instead.

Unfortunately typical {{{stdout}}} printout looks like

and I don't know how to correlate line likes {{{doctest:511}}} with the
original line.
The line in stderr are more useful, but are few and far between
