Instructions
0. Sudo
1. Setup your Clojure distributions, including clojure-contrib
e.g.
root@bowman-europa:/usr/local/clojure# ll
total 8
drwxr-xr-x 8 root root 4096 2011-07-14 19:32 clojure-1.2.1
drwxr-xr-x 6 root root 4096 2010-08-19 11:02 clojure-contrib-1.2.0
lrwxrwxrwx 1 root root 13 2011-07-14 19:37 current -> clojure-1.2.1
lrwxrwxrwx 1 root root 21 2011-07-14 20:50 current-contrib -> clojure-contrib-1.2.0
2. create the Current Extensions dir.
mkdir current-ext && ls -l
bernardo@bowman-europa:/usr/local/clojure$ ll
total 12
drwxr-xr-x 8 root root 4096 2011-07-14 21:24 clojure-1.2.1
drwxr-xr-x 6 root root 4096 2010-08-19 11:02 clojure-contrib-1.2.0
lrwxrwxrwx 1 root root 13 2011-07-14 19:37 current -> clojure-1.2.1
lrwxrwxrwx 1 root root 21 2011-07-14 20:50 current-contrib -> clojure-contrib-1.2.0
drwxr-xr-x 2 root root 4096 2011-07-14 21:24 current-ext
3. setup the clojure contribs as extensions
bernardo@bowman-europa:/usr/local/clojure/current-ext$ ls -l
total 60
lrwxrwxrwx 1 root root 51 2011-07-14 21:19 clojure-contrib-1.2.0.jar -> ../current-contrib/target/clojure-contrib-1.2.0.jar
4. download jline as part of the extensions
curl -L http://jline.sourceforge.net/m2repo/jline/jline/0.9.9/jline-0.9.9.jar > current-ext/jline-0.9.9.jar
5. Create your bin dir and the clojure file (I am using the current clojure distribution to host the bin dir in this example)
mkdir current/bin && curl -L https://gist.github.com/raw/1083942/7b3d784109274820753875e2998f9d80ec100105/clojure > current/bin/clojure && chmod 755 current/bin/clojure
6. Create the link in /usr/bin
cd /usr/bin && ln -s /usr/local/clojure/current/bin/* .
