Clojure installation: starting Clojure fails

Question

I would like to learn clojure and installed it via Leiningen. Startup fails [see below].

Question: how can I start Clojure?

Details: Xubuntu 14.04 LTS 64, java-1.7.0-openjdk-amd64 1071 /usr/lib/jvm/java-1.7.0-openjdk-amd64.

Message at startup:

what version of lein are you on? try doing lein clean and then rm .lein-repl-history. if that doesn't help try uninstalling lein and installing the latest version. — Jake Johnson
I have downloaded lein yesterday, so it is the newest version. I have just reinstalled it now. lein clean gives "Couldn't find project.clj, which is needed for clean" [also after doing "lein new app clojure-noob". Can this be something with Java? — Henk
The problem appears to be that the files that lein needs don't have the correct permissions. as seen here: /home/henk/.lein /repl-port (Permission denied). you'll notice by doing a search that there is an open issue for something that looks very similar to what you are experiencing here: github.com/wuub/SublimeREPL/issues/107 Perhaps one of the solutions there will help you solve this. — Jake Johnson
I have looked at the thread, but the issue there was that a series of messages before startup of the REPL. After the messages, everything works. In the case I have there is no REPL, the terminal hangs. I get a REPL in jEdit, but it does not work. Lighttable does not start. — Henk

solved. solution was to completely remove and purge leiningen, as described here, then reinstall in ~/bin.
