The source code archives (SourceSetup/SourceZip) are missing four files in the Assemblies subdir that the gentlemen who added the respective features didn't care to put into the source setup project. You can get the files either from one of the other distribution archives, from the GDN workspace (source control) or the fixed source code archives from the dasBlog download location. GotDotNet doesn't let me upload the corrected release version right now, so I deleted the source release copy over there for the moment.
