[zope2-tracker] [Bug 539181] [NEW] reStructuredText fails to import docutils.parser.rst

[Florian Friesdorf]

Public bug reported:

- reStructuredText imports docutils.parser.rst
- docutils.parser.rst needs roman
- roman is an optional dependency of docutils which is currently not pulled in

I could not make sense from docutils' setup.py - When installing it into
a virtualenv with easy_install from distribute, it does not install
roman. When using pip there remains a roman.py in site-packages,
however, no egg-info and pip does not tell anything about installing
roman as a dependecy - it seems like a bug, that roman is put into site-
packages by pip.

I think reStructuredText should require roman or require docutils in a
way, that roman is pulled in.
