Just to keep the consistency with other errors in configure.ac, I think it is better to say
like it instead of mentioning the package name. 
Also, there is a python3-docutils and python-docutils depending on the python version
that user is using. So it may confuse the user, and the package name may different
for other distros (I didn't check though...).
