There are couple or gotchas installing the latest  Open Source Flex and AIR SDKs.  Here are instructions to get started

Download the AIR and Flex SDKS

Get Flex from : http://opensource.adobe.com/wiki/display/flexsdk/Flex+SDK

Get Air from http://www.adobe.com/products/air/tools/sdk/

I installed them into /usr/local/flex_sdk and /usr/local/air_sdk

Add their bin directories to your path, in .profile or .bash_profile e.g.

export PATH=/usr/local/mysql/bin:$PATH:~/bin:/usr/local/flex_sdk/bin:/usr/local/air_sdk/bin

Make the compliers executable

sudo chmod +x mxmlc

sudo chmod +x amxmlc

It turns out the lastest version of the compiles scripts are dos terminated lines so you need to do

dos2unix mxmlc

dos2unix amxmlc

You can get dos2unix from macports , sudo port install dos2unix

(bug here :http://bugs.adobe.com/jira/browse/SDK-16699)

Next issue is the samples won’t compile, you will get an error “error while loading initial content”.

You need to update the namespace in your AIR project’s AppName-app.xml file to reflect the new AIR version 1.5:

<application xmlns="http://ns.adobe.com/air/application/1.5">
