One of my favorite aspects of the Clojure community is how quickly it evolves.

1. Install the core ZeroMQ libraries:

    brew install zeromq 

2. Homebrew recently updated its formula for pkg-config to the require 0.25, so simply install it:

    brew install pkg-config 

3. Link pkg.m4 into /usr/share/aclocal so jzmq can find it:

    sudo ln -s /usr/local/share/aclocal/pkg.m4 /usr/share/aclocal/pkg.m4 

4. Build jzmq

   git clone git://github.com/zeromq/jzmq.git
   cd jzmq
   ./autogen.sh
   ./configure
   make
   sudo make install

5. A new trick: Use maven to install the required Zmq.jar into your local repository (located at $HOME/.m2/repositories by default):

   mvn install:install-file -Dfile=src/Zmq.jar -DgroupId=org.zeromq -DartifactId=jzmq -Dversion=2.0.8-SNAPSHOT -Dpackaging=jar

6. At this point, the steps from the previous article take over. Edit your project.clj for the install.

   (defproject my-project "1.0.0-SNAPSHOT"
     :description "FIXME: write"
     :dependencies [[org.clojure/clojure "1.2.0"]
                    [org.clojure/clojure-contrib "1.2.0"]
                    [org.zeromq/jzmq "2.0.8-SNAPSHOT"]
                    [org.clojars.mikejs/clojure-zmq "2.0.7-SNAPSHOT"]]
     :dev-dependencies [[swank-clojure "1.2.1"]]
     ; This sets the 'java.library.path' property
     ; so Java can find the ZeroMQ dylib
     :native-path "/usr/local/lib")

7. Build the project dependencies:

    lein deps 

8. Enjoy!

This process is much refined over the original. It's simple enough now that I was able to wrap everything up into a single installer script, available as a gist on Github. It installs the supporting libraries via Homebrew, builds jzmq, then pulls down a simple test app to verify that everything is installed correctly.
