Title: ritz version

For leiningen the version numbers of plugins are generally specified, while in my emacs config they're not. Depending on the timing, the problems you're having may be down to the lein config specifying ritz 0.4.2 after 0.5.0 was released (and hence downloaded by Emacs).

Try this version, with lein -deps after pulling down to your .lein folder, and see if it fixes the issue.
