How to configure leiningen to use newest Clojure version for repl started outside of project?

Question

When I start clojure repl for specific project, for leiningen is enough to specify correct clojure version in the concrete project.clj file as described here. But when I start repl outside the project then the older version is started. In my case the older version is 1.5.1 and I want to upgrade to 1.6.0. Here has proposed not working solution, but in the comments bellow is said that in lieingen version 2.1 the problem is resolved. I'm with version 2.3.4 of leiningen but the proposed solution doesn't work for me.

If you're starting leiningen outside of a project, would it be better to simply start Clojure directly? Startup will be faster. You could write a one-line script to do this, and even wrap it in a command line history utility such as rlwrap (which isn't as nice as the one that Leiningen uses, however). – Sound

according to technomancy on IRC: "repls outside projects are hard coded 
to lein's version of clojure"

Is this means that the problem eventually will be resolved with the next version of leiningen ? – Glabrate

I don't know about Phil's priorities but seeing that this has been a problem since several versions back I'd say it's not the highest item on the list. Maybe ping him on IRC or comment on one of the fitting issues? – Doralin
