1. Install Ant. Instructions for this can be found here
2. Download Adobe Flex 3 SDK. You can download this here.
3. Unzip the Flex 3 SDK that you just downloaded.

   % unzip flex_sdk_3.zip
   

4. Download the Flowplayer development kit. The latest version of the development kit can be found here.
5. Unzip the Flowplayer development kit.

   % upzip flowplayer.devkit-3.0.3.zip

6. Edit the plugin-build.properties file in the Flowplayer development kit. Specifically edit the line that says:

flex3dir=/Users/api/flex3sdk

to point to the location to which you unzipped the Flex 3 SDK. After editing my file looks like this:

flex3dir=/Users/anil/Desktop/flex_sdk_3

7. Navigate to the example plugin that is contained within the Flowplayer development kit. For me this is located here:

   /Users/anil/Desktop/flowplayer.devkit/example

8. Finally, type:

   % ant

   The output should look like this:

   Buildfile: build.xml
   
   build:
        [echo] ++ flowplayer.helloworld.swf +++
        [echo]
        [echo] checking if flowplayer.helloworld.swf is uptodate
        [echo] main up-to-date: ${uptodate.main}
   
   prepare:
       [unzip] Expanding: /Users/anil/env/flowplayer.devkit/flowplayer.swc into
       /Users/anil/env/flowplayer.devkit/example/build
   
   check-compile-dirs:
   
   check-compile-dirs2:
   
   compile:

   /flowplayer.helloworld.swf (1304 bytes)

   BUILD SUCCESSFUL

Congratulations! You have compiled a flash plugin for Flowplayer!

I am trying to get the AltLaw “stack” working on my Mac OS X machine. So here we go:

1) Download the file http://anilmakhijani.com/altlaw-config.zip and unzip it. I will refer to the location of this unzipped file as {alt-law-config-directory} throughout the rest of this tutorial.

2) Next, we have to get the Rails front end working.

(Prerequisites: sqlite, git)

% git clone git://github.com/lawcommons/altlaw-websearch.gitInitialize altlaw-websearch/.git
% gem install -v=2.1.0 rails
% gem install htmlentities
% gem install BlueCloth
% gem install solr-ruby
% gem install ruby-debug
% gem install chronic
% gem install json
% cd altlaw-websearch
% mkdir log
% chmod -R 644 log/
% cp {alt-law-config-directory}/altlaw-config/rails-config/* config/database.yml
% rake db:migrate

In the file config/environment.rb, change the line:

SOLR = Solr::Connection.new("http://localhost:8196/v3/solr")

to:

SOLR = Solr::Connection.new("http://localhost:8983/solr/")

and:

ExceptionNotifier.exception_recipients = ['errors@altlaw.org']

to:

ExceptionNotifier.exception_recipients = ['myemail@example.com']

% ./script/server

This starts the Rails front end at http://localhost:3000

* To run the Rails front end in production mode do the following:

(Additional prerequisites: mysql)

update config/database.yml with the proper configuration for you database

% rake db:migrate RAILS_ENV=production
% rake sass:update
% RAILS_ENV=production rake asset:packager:build_all
% ./script/server -e production

3) Finally, we need Solr:

The following tutorial seemed to work perfectly on my Mac OS X: http://lucene.apache.org/solr/tutorial.html

% wget http://mirror.x10.com/mirror/apache/lucene/solr/1.2/apache-solr-1.2.0.tgz
% tar xvfz apache-solr-1.2.0.tgz
% cd apache-solr-1.2.0
% cp -r example/ alt-law/
% cd alt-law/
% cp {alt-law-config-directory}/altlaw-config/solr-config/* solr/conf/
% java -jar start.jar

This starts solr at http://localhost:8983/solr/.

This set of instructions worked for me. I would love feedback on what it would take to get this to work on non Mac OS X system.
