I have been trying to install this for months, off and on. Today, I downloaded the most recent code from code.msdn... and re-downloaded the most current version of Enterprise Library. After installation of EntLib, I have no config errors, but the DLLs never made it to the GAC. So, I drag/dropped them. I deployed the feature using the wizard, activated it in my site collection, but when I preview the breadcrumb and search facets parts, I get the message below. I've culled through the boards here but either don't understand what I am looking for, or nothing matches what I've got. I would sincerely appreciate any ideas, before I pull all of my hair out :)
