Yes, that's correct - there is no meta.php or meta2php in RN 2.40.01. Those instructions are for installing nukeSEO 1.0 Beta with PHP-Nuke (primarily those with versions of meta.php that conflict with nukeSEO 1.0 Beta) and earlier versions of RN.
RN 2.40.01 includes nukeSEO DH, a completely new approach for generating META tags that supercedes nukeSEO 1.0 Beta. Although it doesn't have some of the research tools in nukeSEO 1.0, nukeSEO DH's dynamic generation of META tags based on the current page's content and ability to override those tags at multiple levels is significantly better than being able to override META tags only at the site level (as in nukeSEO 1.0 Beta).
We may add some additional features to nukeSEO DH in the future, and we may release it as a standalone for other versions of Nuke or even other PHP-based CMS applications. For now, there is much else to do with RN.
