You need Python 2.6 and the dev-headers of libxml2 in order to run AGX.
Checkout development project by typing
git clone git://github.com/bluedynamics/agx.dev.git
Enter agx.dev and run bootstrap
python bootstrap.py -c [dev.cfg|anon.cfg]
Run Buildout
./bin/buildout -c [dev.cfg|anon.cfg]
When buildout has finished, the AGX binary is located at bin/agx in install_dir.
Run ./bin/agx -i and you get output similar to this
AGX 3.0-dev Development
Congratulations, you can now use AGX.
