I use the Project Manager facility of October CMS to install plugins and themes.
The short answer to your question is that - YES - I have at least tried to install the dependencies but they fail during the installation process with a SQL error. This seems to occur on both the SEO Extensions and Content Type plugins. This then prevents other plugins installing through the Project Manager.
Strange thing is that these two plugins seem to at least in part be installed, but I can't really manage them from the backend of the site.
