WFF 2.2 - Missing Section Error

I'm getting an error when trying to hit a page routed to the farm I'm not really sure the cause of.

     HTTP Error 500.19 - Internal Server Error

     The configuration section 'webFarms' cannot be read because it is missing a section declaration

I've looked at the applicationHost.config file and the webFarms section looks fine.  I've even put the whole thing in an XML parser to make sure there isn't something badly formed or fat fingered. It seems to be ok.

i've seen other references to similar errors for other non-webFarm sections and they mentioned having to add some content. But I have no idea what would need to be added here in this case.

There is the <webFarms> section under <configuration>, and a "webFarms" <section> entry under the <configSections>.  Does there need to be an entry in there somewhere else for that?
