Documentation for 0.9.1 has incorrect version numbers for dependencies.
The versions for the dependencies stated in users/building.rst
have not been updated after releasing 0.9.1. To avoid this kind of issues in the future, I believe that we could (probably) parse this information from the latest profile and integrate it programmatically in Sphinx (I have done similar things in the past with Sphinx and I believe it should be possible). This way, every time that we change a version requirement it would be updated automatically.
