Joe - Have just added the entries into mp_ModuleDefinitions  and [mp_ModuleDefinitionSettings], copying the data from that which is working on a local install, but it's still not appearing in the list.  Is there anything else I should look at?

I have just cleared the system log and rerun the setup routine and this error appeared:

2015-08-02 07:35:59,027 ERROR 82.40.9.29 - en-GB - /setup/default.aspx - mojoPortal.Web.ContentFeature - could not install feature FormWizardFeatureName. Invalid ControlSource Setting. Filenot found: ~/FormWizard/FormWizardModule.ascx
2015-08-02 07:36:28,027 ERROR 74.86.158.109 - en-US - / - mojoPortal.Web.UI.CmsPage - Content is assigned to altcontent1 placeholder but it does not exist in layout.master so using center.

also file permissions could be a factor if it can't read the feature definition file then it would fail to create the data.

the user that is the identity on the application pool needs at least read access on all the files.

my guess is that is because you manually added that row in mp_ModuleDefinitions, the setup page did not do what was intended. It should have also created a row in mp_SiteModuleDefinitions for the master site. You could probably manually add that row.
