This is due to a python2 vs python3 issue. Although the setup.py detects
a python3 installation and does its own conversion of its code, it
misses out processing the docutils directory for some reaason. My
initial workaround has been to do a conversion manually i.e. place the line:
    2to3 --write --no-diffs docutils
into docutils.SlackBuild AFTER the first 'python setup.py install
--root=$PKG' but BEFORE the following 'python3 setup.py install
--root=$PKG'.

This solution "works for me" (solving the same problem which had been
triggered when building python-netaddr). I haven't suggested it
previously because I did notice some warnings/errors when the processed
code was being compiled.

Another solution is to run 2to3 only on the file mentioned in the error
message i.e.
    2to3 --write --no-diffs docutils/__init.py
which also worked for me but made me worry about other unconverted code
in the docutils directory.
