Paths to components are always relative to component root. If your component root is /foo/bar and your component path is /foo/bar than it corresponds to file /foo/bar/foo/bar. It seems that Mason treats this situation as error (as it is very unlickely that a component root is same as a component path) so it produces this error.
Solution: if you want to use a component paths which match filenames use component root == '/' (BTW I think it is default when you use HTML::Mason in standalone mode but I'm not sure). Or set component root to something else and use correct component paths.
