Default version of Sphinx on RHEL 6 is 0.6.6 At the very least, that version is missing the "viewcode" extension currently used in the PulpDist documentation "pip install sphinx" will get a local build working, but it would be better if the docs either gracefully degraded, or else if this doc build dependency was more clearly documented.
Marking all remaining PulpDist issues as CLOSED-EOL It doesn't make sense to leave these issues open, as PulpDist hasn't been in active development for quite some time, and restarting development would involve a significant modernisation effort that would likely render many of these requests irrelevant.
