2. untar it
3. I want it build for beagleboard, so i downloaded recipes_images_beagleboard-demo-image.bb recipe from http://gitorious.org/angstrom/openembedded/blobs/org.openembedded.dev/recipes/images/beagleboard-demo-image.bb and copied that in laverne-4.0.1/meta/recipes-core/images
4. Build!cd laverne-4.0.1source poky-init-build-envbitbake recipes_images_beagleboard-demo-imageand get error as
