@waldenraines this is one reason for leaving off the `.rb`.

> Note that you say require 'filename', not require 'filename.rb'. Aside from looking nicer, this bareword way of referring to the extension is necessary because not all extensions use files ending in .rb. Specifically, extensions written in C are stored in files ending with .so or .dll. To keep the process transparent-that is, to save you the trouble of knowing whether the extension you want uses a .rb file or not-Ruby accepts a bareword and then does some automatic file-searching and trying out of possible filenames until it finds the file corresponding to the extension you have requested.

@ehelms i think, generally, you do leave it off, but i can see this not working because the `katello` namespace is fairly packed full of stuff. It probably looks elsewhere for `katello/plugins` but looks relative to the current file if `katello/plugins.rb` ?
